8GB Mp3 Player That Can Take A Beating?

I want at least an 8GB MP3 player that can take a beating. I had an iPod nano 5th gen 16GB before, but when one of my friends knocked it out of my hand, the screen broke, and then I lost it 2 weeks later, and it's been 2 months, and I still don't have an MP3 player. I'd like it to be small, have no screen, I'd be able to fall of a dirt bike at 60 mph and have it survive without any damage, and take a tumble off a ramp on inline skates without a scratch. Something that's as tough as a brick. What could I get? Because all I see now are fragile touch screens, and stuff with a screen. The iPod shuffle would work, if only it had more memory.
