Aqua? The Macarena? I love those!
...And I have been known to sing along to Barbie Girl when alone...
Generally speaking, though, if I like a song, I like a song, screw what others think.
If Barbie Girl were about something asside from, you know... Barbie, I'd be fine with it.
I love songs I can sing along to. (And I actually learned the words to the Macarena. Yeah, that's right, I did that.)
