If That's What You're Into

I can't remember if it was during high school or junior high and whether it was Eminem or Dashboard (probably Dashboard), but one day my sister came into our room and told me I couldn't expect to feel better if I was constantly listening to music that reinforced how I was feeling.   Explosions in the Sky, Bob Dylan, Bright Eyes, and Iron and Wine are some of my favorites to turn on when I need to zone and just breathe, but when I'm trying to zone out of the moping it doesn't have quite the results I need.   I have a couple of songs I typically use instead such as "I like Giants" or "Superstar". I ran one of my best college race with Matthew Santos's chorus on repeat in my head.  Sometimes you just need more positivity or hilarity in your music. Ie, today's funk was broken by my favorite Flight of the Conchords song. However, I'm overusing the same songs and I'm afraid I'm developing a slight immunity. I need recommendations. What are some of your favorite funk-breaking songs?
