I love the different ways there are to discover music, whether it's a band being hyped on here, Pandora, or even the radio (amazingly, this is how I heard of Anberlin for the first time). Recently, I discovered AWOLNATION, who performed on Mark Hoppus' show (this has actually been one of my most reliable sources for new music - all because of Mark I now know The Airborne Toxic Event and Mumford & Sons to name a few).
Now I really dug AWOLNATION's first song they played, and went to the Internet to scour for some more tunes. To their credit, they had their whole album up on their website for streaming. With the entire thing in front of me, I was able to find out I liked more than just their single and yesterday I bought their album.
