I want a app that allows users to select a song from their itunes and sing along to it for up to a minute.
These recordings can then be posted for the public (other users of the app) to listen too and comment on and rate.
There would also be a battle mode where 2 people use the same iphone and each take a turn singing whichever song they select from the library. When this is posted for the public (users of app) they can comment, rate, and select who was best.
This can be a very simple app to start having minimal features. Basically needs to integrate itunes with the app and the ability to post for others to hear.
