I'm a big fan of the teen soap Hollyoaks. Between the beautiful people and ridiculous high-throughput storylining, I'm hooked. British soaps aren't anywhere near as bad as American ones, but this is still embarrassing...
Another one is the X Factor. I always stop watching after the auditions but can't help but laugh at those initial episodes. Even some of the worse ones sing better than me though...
I also love blowing my brains out listening to Drakengard (especially or some particularly heavy metal on full volume sometimes (with headphones of course). The volume just doesn't go high enough on my current laptop, though, so it's not as fun anymore.
Finally, Bill Bailey's love song.
