Startup Idea : Cover song app/site

I'm a musician. Love guitar and always appreciate hearing a good rendition or new arrangement cover song. Am in early stages of developing an app in which would post 1-3 cover songs daily and people all around the world would be tasked with covering that song. User would rate the top covers of the day and it would all startover again the following day. Let me know your thoughts and if anybody would like to team up on this project with me. Think it would be great to see musicians compete every day and for finding new world talent.
