I'm sure a lot of us would have gotten more of them if we had at least a portion of the melody of the song to jog our memory...
same for me. Got 43,85 (-30% for being a yuppie, +5 points for telling where i found it)
I lived and still love the 80s, but many of them (which i know well) didn't find the matching melody. And, as a german, i often ignore difficult lyrics, if i just like the sound. I just sing some phantasy-words for the parts i don't understand.
Surprisingly i have many songs right with high points but missed much more of the "easy" ones.
cheers, Thomas
