For the 2.1.1 release, which is meant to be bugfixing release (mainly) - no (or at least I don't know about any).
For the 2.2.0 release, which will introduce many new features - definitely there *will* be a sound/music wishlist, but unfortunatelly I cannot give any more details yet.
Oh, and the neverending wishlist for any release is: music tracks for missions.
