I have been trying to remember a song from the 80's and I can simply not find any results. Vocally, I would have said Phil Collins (and style wise, well the chorus at least, I can't remember anything else) but I listened to 20'ish songs and no dice. It's pretty upbeat and all I can really provide lyrically is the lyrics are/can be misheard as "I got over you"/ "I'm not over you" "I'll remember that" to the melody I uploaded, i am sure its a variations along those lines.
