Is there a way so that I can stream audio from my computer's system, music player, etc... to my blackberry, so I could listen to my Blackberry and have it be playing music coming from my computer, is this possible, and if so how?
I don't believe this is possible. It is possible to do the reverse of what you are asking though, stream music from your blackberry to a bluetooth stereo.
You can always purchase a large microsd card and put the music on there, or try one of the several internet radio options such as moodio.fm or flycast. (Just google them both, they'll come up for you!)
