Smashmouth! "Somebody once told me the world was gonna love me, I ain't the sharpest tool in the shed..." I remember I knew this song by heart when I was 4!!!
Green Day (They're old stuff. Nothing past Nimrod!)
Backstreet Boys and Nsync. I didn't really like Nsync, but I had a crush on Nick Carter from BB. *facepalm*
Also, I will spend my day watching my AoStH and SatAM DVD box sets.
And playing Sonic. And Pokemon. *sigh* So many hours playing those. I still have all the Pokemons up til Crystal.
Remember What A Cartoon and Oh Yeah cartoons? And when Disney Channel was actually good? Also, Harry Potter.
I know there's more, but the other stuff was already mentioned...
Man, this topic's making me feel a little old. I miss being little.
