It says that I need Quicktime 7 Pro to download it, but I only have Quicktime 7. Will I need to buy Pro?
No, you do not need to buy Quicktime 7 Pro.
As stated above, right click, with your mouse, on the link to one of the songs, and then click on "Save Target As" or "Save Link As," depending on your web browser. Then, you can place/save the song wherever you like on you computer, and just click "Save."
If your still having trouble, feel free to ask for help.
Cheers,
