Downloading Music, what's the best place?

[Polo]

Hi,

Well, I just wasted 2 dollars, 1 in napster.com and the other one in itunes.com, I downloaded the software and everything I went ahead and bought a specific song I like from napster here at my school and then I took it home (where I dont have internet access) tried playing it in my windows media player and I cant play the dumb thing....

I thought i was an mp3 but the thing is protected or something so wont play neither on windows media player or the napster software at home (when I try playing it, it will look for internet conection)

anyways, so the next day I do the same thing... but at iTunes bought the song (same song) tried playing it, but itunes uses m4p or something like that, so it wont play on windows media player and when I try to play it on the itunes software it will look for internet access...

is there a place where you can just buy a simple mp3 and play it wherever you want without having to have internet???

I was going to go to yahoo music center.... but wanted to ask for advice here..

maybe someone can help me with this one...

thanks...

anyone?
