I spend much of my life sitting at a desk. I retain my version of sanity by listening to music. The internet is my friend. It constantly improves my access to music. If you like music, you should check out these sites that are either new or have improved recently...
Good for studio stuff. Listen to anything they have once for free. Less than $1 to buy the right to listen to something over and over on the web. iTunes prices to download. Kinda fun because you can create an account, invite friends, send recommendations track what people are listening to, etc.
Might just be the best site on the internet. God of live shows. Unlike the Live Music Archive, it has tons of Phish, especially really old stuff. New host makes it more reliable and easier to use.
