Even though I'm not a fan of 90's pop now, I sure was when I was a kid. Matter of fact, my memory is so good that I remember just about all of the words to any Backstreet Boys, N'Sync, Britney Spears, Christina Aguilera, Savage Garden, (etc.) song. I also have a few Enrique Iglesias songs memorized just so I can start randomly singing it to get some laughs. In the end, I don't restrain myself to a certain genre(s). I listen to just about everything (excluding screamo and metal rock).
I'm also a big Justin Timberlake fan...
