Lewandowski's original goal was to build the most comprehensive database of electronic music, organized around the artists, labels, and releases available in electronic genres. In 2003, the Discogs system was completely rewritten, and in January 2004 it began to support other genres, starting with hip hop. Since then, it has expanded to include rock and jazz in January 2005 and funk/soul, Latin and reggae in October of the same year. In January 2006, blues and non-music (e.g. comedy records, field recordings, interviews) were added. Classical music started being supported in June 2007, and in September 2007 the "final genres were turned on" – adding support for the Stage & Screen, Brass & Military, Children's, and Folk, World, & Country music genres, allowing capture of virtually every single type of audio recording that has ever been released.
