Here are some links that are worth checking out...i guess...

Music Places
Sheet Music Even though this isn't a free sheet music service, it kicks all other's asses. It's really hard to find really great sheet music (besides tabs) on the internet, so, eventually you realize "I'm not gonna waste my time-- I'll buy it." Most music here comes with a free sample page anyway, the midi of the song, and if you download it, a great sheet music program where you can watch notes light up as their being played and it has a guitar tuner in it, too, and basically, I love this site.
Punk/Hardcore Tabs Great selection of tabs...huge assortment, even if a lot suck (free)
Thouroughly Modern Millie The best musical ever besdies Show Boat, and, I mean, Showboat is a classic so nothing CAN sompare to that. Anyway, I saw it 8 days after opening night a few weeks ago, and it's nominated for a crap-load of tonies, and it's just amazing. I saw Catherine Brunnell as an understudy for the lead, but she was amazing anyway, cuz I saw her as Eponine in Les Miserbles and loved her there too. K, GO SEE IT, IT'S HILLARIOUS

Other Sites
BLibs It's just a mad libs site, but they're so fun to do and you can send them to your friends and stuff
Stick Man Dance It's basically stick men dancing to the Cotton-eyed Joe song


Mr. nice Man, I can't even begin to describe it...one of those "see it to believe it" things
