Jaikoz uses MusicBrainz, an online database of over eleven million songs and Discogs another database of over 3.5 million releases. Many of the songs also have an Acoustic Id provided by Acoustid, allowing a song to be identified by the actual music, so it can do a match even if you have no metadata! These feature means that Jaikoz gives you the flexibility to lookup your songs by both the acoustic id and the metadata making Jaikoz a very accurate tool. But no identification system is 100% accurate so we have made it as quick and easy as possible to edit your data manually as well using a convenient spreadsheet view, with many autoformatting features.
