ProjectPlaylist is a safe, legal site where you can listen to any song you want to, but you are not aloud to download any music. Another one of the features is that you can make you're own personalized playlist to put on you're MySpace, FaceBook, GaiaOnline page and etc. You can find even some of the rarest of songs!
Manga Volume is a good site for reading online mangas, Japanese 'grayhic novels' AKA comic books. It is known by many, but sadly the limit to mangas on the site isn't really big.
If one more person says GaiaOnline is an emo site they must be pretty stupid. Yes, there are many emos on GaiaOnline but there's alot of emos everywhere. Anyways-- Getting to the point; GaiaOnline is a cool little site with many forums and forum catorgorys and many people with you're same interests! You can chat with them, make you're own personalized avatar, and you're own personlized page. Not to mention comics and art. The only sad thing about this site is the fact that you can do almost anything you want on that site as long as you have enough GaiaGold in you're account and the admins don't catch you! XD
