Me loves Lights, so nothing to be ashamed of, man. I still sleep like a baby to Backstreet Boys songs just because before LP, they were my favorite band ever. XD I also dig Ke$ha's "We R Who We R" just because it's catchy lol
I can listen to anything and everything and I'm not really embarrassed. I'm listening to Paparazzi as I write this
I still listen to songs by a1 (European boy band) and t.A.T.u. Sometimes you can't really argue with the catchiness of pop.
