Falling asleep

I've been listening to my work-out playlist on my Sony Walkman NWZ-W202 (thanks Guha) for far too long now. The Walkman is so convenient I end up listening to it all the time. I think I'm slowly getting used to it as background music. The other day I wasn't able to sleep until I plugged it in one ear. And the playlsit isn't exactly a soothing one.

Do I need to be concerned about this?

Fuck no, I've always wanted a soundtrack to life.

Edit : Had exam#2 yesterday, let's see how that pans out. Another day older, deeper in debt.
