Donna Summer - On the Radio: Greatest Hits Volume I & II: 9 (A)

I could upgrade to 1994's Endless Summer, but this is the original. The later one is missing 5 tracks from this, and adds 8 of its own though, so maybe I'll get the new one too one day. (They're both about 71 minutes, so the later one obviously has shorter songs overall.) On the other hand, the later one seems out of print now, so I'll pass for the moment. Hull and Christgau give each one the same grade (A minus and full A, respectively). [Update: went for Endless Summer after all.]
