Live/Die by the Sword - Jamestown Story (formerly "And Then I Turned Seven")
Life's a Slice - Forever Means Never

Both bands are pretty "indie" so it might be hard to track them down.

Edit: And no, you're not strange at all. I do the same thing sometimes. Actually my friend got me both of these songs because he knew they'd likely help me out if I wanted to SI. So you're not alone.
