 Many remix services have focused on a specific style of music (such as hip-hop or rock) or type of remix (such as house mixes of pop hits).As of 2006, there have been over 50 official remix services worldwide with at least as many spinoffs, although most of these companies (including Disconet) have long since folded due to financial or legal reasons.All remix services are required to get the original record label or artists' permission to edit and release a track, but many bootleg services exist that do not.
