I have about 1.5 Terabites of music, and music videos on a portable hard drive. That can be hooked to anything with USB and goes from 1920's to Current stuff not fully released. To Fully "DJ" I need my DJ Mixer and Digital Turntables, which is the expensive pieces not good with sand. Playing music is easy... an iPod can do that, DJing is totally different. I'll bring a back up Drive with some music. I like the XM idea though. Easy to change around so more people can here stuff that they like. Pandora channel even works for Mike and I at the shop and we have TOTALLY different music preferences... lol.
Totally get ya @@dunefreak.
Looks like I will be bringing a new RZR XP1000 out with me... it's not mine, but i'll probly use it once or twice.
