MPS is a new tool I have discovered a couple of weeks ago, that one can use to stream (and download) Music from online sources (apparently coming from Pleer.com) similar to what you can do with Grooveshark already. The difference is that MPS is a command line tool, and therefore you don’t need to load a heavy browser in memory to actually start playing music with your Pandora. And just for that, it’s a great solution. Plus, it’s extremely simple to use, even if you hate the command line. But it can also do a whole lot more.
