Glee... I'd been meaning to watch this one after seeing some previews online and totally forgot about it. Fortunately FOX has the sneak peak episode online in it's entirety - complete with a player that plays the entire show, not annoying seven minute segments. Only a few, FOX related quick commercial interruptions, too. Nice.
Glee doesn't come until the fall but I loved the preview episode. After watching SYTYCD, I was on a musical/dance high and Glee did a great job of keeping that going. The series doesn't air in full until sometime in the fall, but I'm thinking it will be a nice nicotine patch for the end of the dancing show.
This kind of entertainment totally improves my mood. I love shows like that - ones that totally distract you from reality, sucking you in to some other universe where everyone is an amazing dancer, the music is great and there are sequins and glittery costumes everywhere :)
