Can I record using accompaniment tracks?
Yes, but you'll first need a master use license from whoever owns that accompaniment track.
Permission to modify or duplicate a sound recording is separate from the permission needed to record the underlying song. You can usually identify the sound recording's owner by locating the ℗ symbol. Note that the owner of the sound recording is usually not the same as the owner of the song.
Studio Series tracks distributed by Word Music, LLC cannot be licensed for recordings.
