Amazing classic.
The first time we really got the hang of it we started making amazing beats and rhythms that practically made our hearts jump inside of our bodies.
I'd highly recommend it for novice music makers at best, but I have no idea if there is any royalty-free license behind it, I will have to check up on that personally.
It should also be noted that this is one of very few music programs to feature "video" options in which you can make your own unique video based on pre-textured images with special filters. The end results can sometimes be more than astonishing.
I'm being a bit dramatic, sure, but it's seriously a good buy. It's also rare, apparently, because the only place I've seen it is Sam Goody and they only had one copy of the game itself.
It was the best purchase my friend ever made music-wise, because we've never regretted owning this game.
Refuse to go 10/10 out of knowledge that perfection doesn't exist in this world.
