If I'm not mistaken, it was "Dammit" by Blink182. Haha.
I felt so proud of myself; I could actually play a song that me and my friends recognized. Just good times.
After that, the first "complicated" song I tackled was "Californication" by RHCP. The album had just come out and I was desperate to play something from it. I thought "Around the World" was too hard for me, so I sat down and started figuring out Californication by ear. It took forever, and a lot of it was wrong, but, man... the feeling I got when I played along with it was incomparable.
