NOPE ! its not a waste to me . but then the way i see it Americans cant make pop music . ( yea meaning i only listen to pop music if its Japanese , & sometimes i still dont like it . ) any ways iv got a few soundtracks and i listen to them all the times ... really i dont understand why itd be a waste . if your just asking ' how do you know whether youll like it or not ' then the answers really obvios ; either listen to the music when watching the Anime or go online and search for samples of songs from the soundtrack your looking for .
