In case anyone reading this has some actual time on their hands (yeah, I know...but it is possible!), here are a few nifty sites to check out:

Free iTunes Downloads
You may not know it, but the Apple iTunes store regularly offers free singles. The problem is finding them. This intrepid blogger keeps track of the free stuff and even posts reviews to help you figure out whether or not it's worth it to bother making the effort to download it.

The Whitest Kids U'Know
Obnoxious, hilarious, offensive, and a little rough around the edges, this sketch comedy troupe from New York will definitely make you laugh. Not for the easily offended or humorless.

Gabbly
If you're the type who has something to say about everything, you'll want to check out this site. Just pop a simple URL in front of the address of any site you want to chat about and you'll be jumped into the Gabbly chat room for that particular site. But don't think it's totally useless: it also makes a cool QA tool or client demo tool if you want to show off one of your own sites.

Pandora
If you're looking for new music, are sick of commercial radio, or just want something to listen to while you work, check out Pandora. Simply put in the name of a song or a band that you like and Pandora will automatically generate a personal "radio station" that plays music like the band or song you entered. Great for discovering new stuff!
