Song artist shown as Artist?

[brooke82]

I've noticed that randomly the song artist in the dancing screen will be listed as Artist instead of the artists or groups name. This has happened several times, and I apologize that I didn't keep track of the songs that it happened on. I'M A BAD NERD!! I'M SORRY!!! But I swear that I speak the truth.

It's only one song, "Drive".

I was wondering if the artist was actually "Artist" or if it was a typo. :P
