Music is anything with a beat. It can be instrumental (classical, jazz, film scores, etc.), any genre with vocals, etc. It counts as long as it has a melody to it. Other types of recorded albums that are talking rather than singing (comedy shows, spoken word albums, motivational cassettes, etc.) are pretty much the only thing that don't qualify here. You are encouraged to embed a video or post a link to the songs you choose so others can listen to the track!
