Music

MySpace profiles for musicians are different from normal profiles in that artists are allowed to upload up to six MP3 songs. The uploader must have rights to use the songs (e.g their own work, permission granted, etc). Unsigned musicians can use MySpace to post and sell music using SNOCAP, which has proven popular among MySpace users. Shortly after MySpace was sold to Rupert Murdoch the owner of Fox news and 20th Century Fox in 2005 ^[29]they launched their own record label, MySpace Records, in an effort to discover unknown talent currently on MySpace Music. MySpace Music is a section of the website that allows its users to display their songs. It doesn’t matter if the artist is already famous or still looking for a break into the industry; aspiring artists can load their songs onto MySpace and have access to millions of people on a daily basis. Some well known singers such as Lilly Allen and Sean Kingston gained fame through MySpace. The availability of music on this website continues to develop in the foundation of young talent. Over eight million artists have been discovered by MySpace, and many more continue to be discovered daily ^[30]
