Yesterday I downloaded the DT and Quicktime - great to have all the songs but, like others above, no sound. I twiddled a few things today and now the sound works!

Don't know what I did, don't think it was anything to do with the actual files - just pushed a few more buttons, including the "start" button multiple times, other keys, etc. (Yes, I kick pop machines too.) Also copied the DT into another folder on the same drive as Quicktime but now I've deleted that and the sound still works. I think the little PC elves just took a while to decide to let me hear the tunes.

Now I'm off to check out more songs ...
