Maybe my mind is just weird but I make associations between people and various things, not just songs.

The songs I associate with people only inspire negative feelings. Mostly they trigger an incredible anger....

• "Your Star" by The All-American Rejects + "Promise Ring" by The Tremolo = My emotionally abusive ex (who I was planning to marry before I realized his abuse)
• "Freakish" by Saves the Day + "Blue and Yellow" by The Used = My psychotic college roommate who I cared for (naively) in the same way a psychiatric nurse would... The stress and inevitable failure with the situation triggered my depression.
• "I Gotta Feeling" by the Black Eyed Peas = The "theme song" for my grad school class... A degree that ended up being unusable because the school screwed up.

Ironically, "Panic Switch" by Silversun Pickups usually brings on a panic attack in me for some reason.

However, the worst musical association for me is anything by the band Vertical Horizon. They were a friend's favorite band and after she was killed, I couldn't hear their music without crying and, if I heard it in a store, having a sudden urge to run out of the store. It took me 15 years to stop crying when I heard their music and I'm now attempting something like exposure therapy to stop cringing when I hear them. I think it's working...?
