My previous post hasn't been validated on muselive (yet?), but i've uploaded it to sendspace for everyone to download.
I ripped this personally directly from the app. It IS in stereo. It IS good quality. The MP3s are encoded at 256kbps, which is more than adequate for the quality that is present on the app, any higher (320) then you're just increasing the file size and not retaining any higher quality, 256k is more than enough.
They are ID3 tagged (with no artwork, you can choose) so they line up and group in iTunes perfectly fine.
