For grace notes in music, see grace note.Gracenote is a company which maintains and licenses a database of music and movie metadata. The database is accessible online over the Internet. As of 2005 many computer software applications that are capable of playing CDs or digital audio files use Gracenote's CDDB or similar services. These programs generally offer the option of allowing users to directly contribute information to the database. Gracenote's data was initially created this way, though now much of their data comes directly from record labels and numerous other sources.
Background
Gracenote began in 1993 as an open source project involving a CD player program named xmcd and an associated database named CDDB. xmcd and the CDDB service were created by Ti Kan and Steve Scherf, respectively. Because CDs do not generally contain any digitally-encoded information about their contents (see CD-Text), Kan and Scherf developed software which identifies and looks up CDs based on TOC information stored at the beginning of each disc. A TOC, or Table of Contents, is a list of offsets corresponding to the start of each track on a CD. The matching is fuzzy and tolerates some variation in track offsets.
Some computer users who have copied vinyl LPs from their turntables onto CD-Rs have been astonished to find their computers correctly displaying the titles and track listings when these CD-Rs are played on their computer. This happens when a commercial CD is a remastered version of an LP, containing the same tracks in the same order. If the track offsets of the homemade CD match the track timings of the commercial CD to within a second, the CDDB database can identify the CD successfully.
Gracenote got its start as a CD recognition service, but has since introduced a wide variety of recognition services and related products. The first of these was MusicID File, released in 2003 and based on technology purchased from Cantametrix, which offers recognition of digital audio files such as MP3s and other popular file formats. In addition, Gracenote has included DVD recognition in its repertoire. In 2005 Gracenote purchased audio recognition technology from Philips that is highly tolerant of noise, and allows for the recognition of music over a cell phone microphone. It rolled out this service as Mobile MusicID. Gracenote also offers a number of B2B and consumer-side products such as playlisting logic (Gracenote Playlist), third-party database linking for delivery of additional related content (Gracenote Link), among others. Gracenote products are offered for use in PC applications, as embedded products in consumer electronic devices such as home audio components and car stereos, and for use in cell phone handsets.
Commercialization
In 1998, Kan and Scherf sold the assets of CDDB to Escient, a producer of high-end consumer electronics. CDDB was later renamed Gracenote. The maneuver was controversial, because the CDDB database was built on the voluntary submission of CD track data by individual users. Initially, most of these were users of the xmcd CD player program. The xmcd program itself is an open-source, GPL project, and many contributors assumed that the database was free as well. Though Gracenote has never charged end users for access to the database through its online service, it does charge commercial developers a fee for the benefit of using its service.
In 1999, freedb, a clone of the Gracenote CDDB service, was created by former CDDB users who wanted a noncommercial alternative. The track listing database freedb used to seed its new service was based on the data previously released for public use by CDDB. Nevertheless, some users remained angered by Gracenote's commercialization.
As of 2005 Gracenote claims that its database contains information on almost 4 million CDs. The reliability of this statement has been challenged. Because the manufacturing process for CDs introduces fuzziness to TOC matching, duplicate entries are very common. An article from the Knight Ridder news agency cites Ty Roberts, chief technology officer of Gracenote, as saying that there are approximately 500,000 individual CD titles commercially released and available for sale today in the United States. This number does not include CD titles available worldwide, and may not take into account CDs that are out of print, or demo CDs that were never available on the open market. Also, Gracenote allows the submission of personal home-burn CDs, which may contribute to their high count.
Lawsuits
In 2000, Gracenote sued Roxio for breach of contract when Roxio switched to freedb, allegedly violating its contract with Gracenote in the process. The case was settled in 2002. Though terms were not disclosed, Roxio acknowledged that it had renewed its license to use Gracenote's service.
Gracenote v. Musicmatch
In 2002, Gracenote filed suit in the Northern District Court in Oakland, California, against MusicMatch, another former licensee, for breach of contract and patent violations. Musicmatch filed a counter-suit against Gracenote. A summary judgement found that Musicmatch's replacement service does not violate Gracenote's patents. The court also found significant evidence that Gracenote may have obtained its patents fraudulently. In a subsequent bench trial, the court found largely in favor of Gracenote, citing no evidence of fraudulent activity on Gracenote's part. Additionally, the court reversed its findings on numerous points in the summary judgement. The case was to have continued on to to a jury trial to determine whether Music Match was in violation of its contract with Gracenote. The case was dropped by both sides during jury selection when Yahoo, one of Gracenote's customers, announced its pending purchase of MusicMatch.
A growing group of companies continue to enter the media identification and metadata marketplace.
Similar services
Many of Gracenote's small former licensees moved to non-commercial services such as freedb, citing claims of restrictive terms and anger over the privatization of the company. At least one large commercial licensee dropped Gracenote's service, such as Musicmatch. Some have subsequently switched back to Gracenote, after the freedb founders parted ways over a dispute about commercializing their service.
The AMG LASSO commercial media recognition service allows for the recognition of DVDs and digital audio files such as MP3s, as well as CD recognition, and directly competes with Gracenote in online and embedded device markets globally.
MusicBrainz is also another music identification service that is open source and created by community contributions.
