Since you have both Whitney Houston & Dolly Parton for "I Will Always Love You", you could also accept the covers that UB40 did for "Baby, I Love Your Way" and Marilyn Manson for "Tainted Love".
They were called The Supremes when this song came out. They didn't change to Diana Ross and the Supremes until 1967, and Diana Ross didn't go solo until 1970.
Not certain, but I'm guessing the rather odd order, as well as the selection of songs, is based on the number of Spotify plays - since that's referenced in the instructions.
Could that be an age thing? Ya' think?
