I'm not being funny with you, I'm just giving you (and anyone else) some advise. Right now people have found ways of cracking it. While this will probably always exist, it's illegal, so you might as well just have downloaded the music from some P2P service.
The companies that sell DRM'd music are under no obligations to keep making software or devices that play it back. Take Microsoft's new Zune player for instance. It uses a completely different DRM system than the other Microsoft system used by everyone else but Apple, called PlaysForSure. Essentially Microsoft are pitting their Zune against all the other companies like Creative. When PlaysForSure dies (and it will do one day), only current devices that support it and current software will play your music back. If you buy a new player or upgrade your software, you may lose your music too.
DRM is pure evil, and the problems it's going to cause have yet to properly be seen.
