Need suggestion about music player


Hi all

I'd like a music player program could run in the background, so I can press a hotkey to play / pause music while do otherthing, such as do a leave streaming, and press a hotkey to play or pause the music file I loaded before. My need is similar to the multi media keys in a physical keyboard. If you know any, please suggest, or if you need further info to give better suggestion ,please leave a message.

Any help would be appreciated.
