If not which one should I get?
Also, can I stream to my Jeep radio via BlueThooth
There should be a stock music player - although I never seem to use them...PowerAmp is a nice 3rd party player or if you want to store all of your music in the cloud - check out Google Music...you can set the account up on your computer (using your gMail account)...
**Be yourself - Everyone else is already taken**
I use PowerAmp to play local music, AudioGalaxy to stream from my library on my desktop and Slacker for everything else. I've been playing around with Sonic because I'm looking to move from Windows to Linux on my desktop.
