Do you know what an earworm is?
It's not a creepy bug that crawls in your ear, but rather "a portion of a song or other music that repeats compulsively within one's mind." I'm not making this up. It is a legit term.
Studies show that everyone has been affected by earworms, however some people are more susceptible. Count me as one of those people.
Here is a classic earworm of a tune for me. I previously talked of my friends' odd obsessions with Third Eye Blind and this is a classic example of Third Eye Blind's pop/alternative vibe.
