Grooveshark is the ultimate in internet music.
Go to Grooveshark.com, an internet radio website, and see what I mean. You can pull up some general categories, but even better, you can just type in your favorite artist or song into the search menu and Voila! There you have an album that you’ve been dying to hear. Now, currently, one problem is that it can hog some memory if you have a ton of songs in your list. Still I like that you can go to GrooveBackup, create an account and periodically backup the list of songs that you so brilliantly put together.
I hear that the new music playlist keeper is Spotify and that it has proven itself in Europe. I’m off to try that one next.
