No worries. If anyone else wants one, I've got 7 more. They keep popping up, but are useless for my friends (in the UK, invites aren't required).
I don't know what Pandora is, but basically you search in a Song name or a Band name and it'll come up with the song results then you just click on the song you want and listen.
Pandora is basically "search for a song/artist" and it creates a "radio station" based on your inputs. It's great for just some jams to listen to based on whatever you're in the mood for, but basically useless if you're trying to listen to a particular song.
It's an advert-funded music streaming service that allows you to listen to thousands upon thousands of albums from both big and small record labels for free.
It's a great piece of software, but the damn thing doesn't work here anymore. I used a trick by signing up with a UK proxy and then changing my location to the Netherlands (so i didn't have to log in every two weeks with a proxy), but recently received a mail that Spotify free isn't available in my country while it did work for the last 4 moths or so. First Last.fm, now Spotify. I need music streaming! Blargh. Sorry for the rant.
