Check out
foo_sendtodevice as long as your player supports MSC (standard USB) connections. If it is MTP-only, an iPod, or some other device with a proprietary connection protocol (earlier Creative players, maybe?) then I don't think you'll find anything for foobar. You essentially need a drive letter assigned to the player storage for foo_sendtodevice. If you have questions about it, I would direct your inquiries to that discussion thread.
