I wish I had a song stuck in my head that actually had lyrics

Is it me, or has anyone else ever realized they've been listening to the same type of music for a few weeks now? After being on Pandora and it playing Sandstorm, I realized I've been listening to almost exclusively dance and trance music. It's mostly because of two OSTs I've been listening to are also of the dance variety.

Also, I have been playing Animal Crossing on my Nintendo DS for the past week.
