Which music download service?

Ok i downloaded bittorrent again n then went to mininova and searched for some music, clicked "download this torrent" which opened up the wee "downloads" window and the torrent was in there but it was a tiny file compared to what mininova said the size was so i right clicked and selected "open" and "opera" opened up which seems to be a download thing like bittorrent right? I never downloaded opera though, is this the default service that mininova uses or what? and if its gonna use opera then do i need bittorrent?

you might need to change your default bittorent client to whatever it is youre using. Im on a mac and I use transmission.

+1 for last.fm

+1 for downloading music until you know its good and then going out and buying the album.
