I love Gold Rush too! And Feel so Free by Ivy. That song is so relaxing. Of course, who could forget the theme song. That is by far my favourite song ever! Really, it is. I listen to it almost everyday and The Dandy Warhols just rock! My parents (let's just put it this way, they're not young) love it as well. My dad actually started dancing as I was playing it. Embarrassing, yes but cool none the less!
ETA - I totally forgot about Momentary Thing by Something Happens. How could I? It's the kiss song!
Every time I hear it, I get the biggest smile on my face. The kiss replays itself in my head. Plus, it's a really good song to boot.
