My band is gonna be putting some recordings online fairly soon, for posterity's sake (I'm graduating and moving back to Chicago at the end of May). We were thinking about using MP3.com, but a friend who produces electronica has indicated that IUMA is a lot more useful. What are your experiences with these two? Will either of them allow us to use non-original material? We do a killer cover of "Red Clay" but we don't want to have to contribute to the Get Freddie Hubbard Some Blow Fund.
