I'd have to say, anyone that spends all day on computers, and wants to listen to music should really look into Pandora. Pandora on the blackberry = better than sliced bread.

Yeah I have that app and the desktop player too. I have a built in last.fm player in my firefox so I tend to use that more than anything on my desktop. Last.fm is a bit easier to use than Pandora, but Pandora plays better music more often.

Theres another one called Slacker that some say is better than Pandora but I have yet to give it a try.
