How do you guys store your music and in what format?

[DonP]

downdoad iTunes to your computer, its free. Connect your iPhone to your PC, import whatever CD you have or any audio files on you computer and try it out. Then use the iPhone's as an iPod. I haven't imported all my stuff but I thinks it cool as hell as I can buy whatever song/album from iTunes right from my phone. I bougth a lot of old stuff I had on vinyl and can listen in my car stereo or anything really.

I was thinking about doing that until I saw how much iPhones were selling for on ebay
