I like having music available anywhere I go. I also like to freestyle. I'm looking for a web app that has a good selection of rap beats. Really I want something that has a shuffle mechanism, where it will play a random one.
On Pandora, the best I could find were hip hop instrumentals, and the selection was very limited. I need it to be free. I don't mind making an account and having to log in to use it, but not registering is better for me. I'm running out of search queries to find something like this.
Where can I find such a service?
