Playing music from a usb stick

Thank you so much for a speedy reply. I have tried that but the files seem to be descriptions of each track rather than anything I can recognise as playable. I thought I'd downloaded the songs correctly from my old pro, but obviously not! I've just tried saving a pages file to the stick on the air and that worked fine so I must have done something wrong on iTunes on the pro, but I don't know what. So frustrating. I feel I'm almost there, but just not quite.

Yes. Same ID. I thought I'd copied the library, and the file certainly is a list of all the songs but along with loads of code I don't understand. I'll have a go at dragging it and see what happens. Thank you again, very much.

Wow! Huge thank you for making it so clear. The library won't automatically download to iTunes because the file is too big for my air, but all the music is there and I can play it. Hurray! You've made an old person very happy.

Yes. You may be right, though when I bought the MBA I did try to move all the music across and it said the file was too big. The USB stick is (now, thanks to you) a perfect answer.

And you're from Toronto! My favourite city that side of the pond.
