I don't usually download any new music and, if I do, I use LimeWire (and then I disconnect from it, so I'm in and out fast) (it's not a website but I don't want to get into too many details here because I know it's all probably illegal -- yeah, probably, haha). The only reason I even download any newer music is if I like a song that I heard on TV.
I don't buy new CDs, unless it's something like a greatest hits CD or maybe world music or New Age type of stuff. In fact, I can't remember the last time I bought a CD. I own nothing that's on the Billboard charts right now, LOL. I have a collection of my own that I like a lot. I've never counted how many CDs I have but it's probably around 400. I could spend days just downloading my own stuff, and I will, one day, if I get a large capacity MP3 player.
I had been looking to buy an 8 gig player but I'm wondering if that's going to be enough? I don't even use the MP3 player that I have (1 gig) which is why I hesitate to buy anything new. I have a Sandisk It's nice but I'm in the mood for a new toy and I'm waiting for my government rebate check! (unless I get laid off ... which is always a possibility since they're doing lay-offs in my firm)
