@ Hawk: That song's in my brain forever, too... such an awful(ly catchy) jingle...
There are tons of video game songs I prefer, but I must admit that I find the new SSBB theme really, really catchy. I hum it without realizing it.
It doesn't help that there are about 300 variations on the song in the game itself, and then when I found the youtube videos putting "misheard lyrics" to the tune, it was over.
Omelet prevail!
