I don't know if Apple has anything other than iTunes, but there's a wide choice of software for cueing up and playing music on the PC. I wonder what everyone prefers these days? I like Foobar at the moment; I'm not really into playlists and other features but I like this as I can just drag files onto the player as and when I fancy it. It's very customisable but perhaps a bit too complex if you want to delve that deeply. Foobar has a nice program for Android too (I cannot bring myself to say App - ugh).
