Rumors of Apple opening a cloud-based music storage system just won't go away, and now The Music Void says that a "locker" system that sounds very much like what we've heard before is coming with the new MobileMe, which is expected sometime in April.
Warner Music Group has reportedly already agreed to get in on the service, with Apple attempting to bring other major music labels into the fold. It's not clear, but this could be the streaming service that would provide backups of downloaded songs that earlier appeared in Bloomberg reports.
Whatever it is, the latest rumor says it'll cost about $20. That could be a reasonable price, though it'd be easier to judge if we actually knew anything concrete about it.
