There was an article in the NYTIMES a couple of months ago that featured at least one of these sites http://www.boomselection.net/ or http://base58.com.

Basically they take bits and pieces from familiar pop tunes and merge them together somehow. Even with the right software, it seems pretty tricky trying to match up rythym, vocal and harmony just so.

Anyway, they released this cd, http://boomselection.info/thecd/ that's already backlogged with orders.

Anyone here that follows all that stuff?
