I think you should check it out. With its small size of less than 500 megabytes it can be used as a back up OS that can be stored on almost any flash drive. There's also a community around it. I used Universal USB Installer to install Puppy Linux onto my USB.
I'm not interested in playing instruments, but I like game music. I think The Sims 2's soundtrack is unique and interesting due to the instruments it uses for each song.
