I'm using Premium on a 30-day free trial. My computer is an iMac from late 2009, OS: El Capitan. I'm concerned about downloading, especially full albums. After creating a playlist of three items I tried to download it and was "successful". However, when I checked the location I found that I had only managed to create 33 folders, of about 9 MB, but impossible to open (no, I didn't check all of them). I have tried other locations as well, e.g. Music/iTunes/iTunes Musc which harbors all the files in my iTunes library, and a folder on Desktop. Same thing there. The names of the folders are two characters, such as ff, b2. Wha could the problem be?
