To clarify: This DLC is strictly if you want the MP3s/WAVs of the songs. If you wanted in game bonus items then this is not the right one for you. That being said I really like the songs and the alternative versions and if you ever wanted to hear Poppo sing then get it. If you like the song when you play your hyper then get it. If you wanted Sham/Sora/Instrumental versions only then get it. Otherwise you can avoid getting it.
