Lots of resources and promotional services. Cute ReBirth-like interface. Resource site about music scams, funny royalty calculator, good articles. You have to pay for personal consultation, but a lot of stuff here is free. Great stuff, though the font is too small and can't be adjusted.
Site offers other good resources, too.
Offers opinionated and insightful articles and interviews, also a music news site. Good place to send your press releases to as well. Clean, smart site. Good for keeping abreast of the top web sites, seeing how many hits they report per month, etc. Simple but good links to record company sites, etc.
