Mp3 player question?

mkay this is a lil question bout mp3 players. I'm think bout gettin one. the one I like isn't that high in price and even has pic. well my question is about legal and illegal music downloads for them. I know I've heard of sites that have illeagal music...

and then those who download it get in trouble. so what are some legal sites I can download from once I get it? and how much do downloads run?
thanks for any help

itunes is a legal one and cost .99 per song I think. Limewire is another site, but it is free but I guess it is still legal.

ok thank you
