Daft Punk feat. Pharrell Williams - Get Lucky
Probably the song of most people's year. It's a little earworm, be warned!
New Kids On The Block - Remix (I like the)
Another earworm. This also became my own signature tune... it always makes me feel happy when I hear it, motivates me when I'm exercising and generally makes me dance around like a loon.
One Republic - Counting Stars
All of my Top 3 are total earworms. This is another. As expected!
