Although, you could count Emily, whom Revan listened to, and I also tried listening out of curiosity (maybe I was looking for something specific, or maybe I stumbled upon it somewhere, I don't remember). But I don't listen to everything, just a few songs.
There was also a story with Muse, when my brother's friend gave him a disc with various songs, and there were three Muse songs on it. I started listening, then downloaded their albums, and now they have a special place in my collection.
I used to hear songs on the radio (a few times online) and discover bands that way. But mostly, I find them through TV, especially A-ONE. I've found many good bands that way. And of course, I use Last.fm. I search for bands in similar artists, then I add them on VKontakte and listen to their songs. I add what I like, and over time, I download the albums.
