Collins had that deal where I believe he did a Genesis album, then a solo, then another Genesis album every 4 or so years, so there was definitely no shortage of material. A lot of people think Genesis songs were Phil Collins, too, which is technically true. “Invisible Touch” and “No Jacket Required” are two of my favorite 80s albums and I enjoy seeing a lot of the tracks still popular on FM. “Tonight, Tonight, Tonight” is another good track off of IT that I had forgotten about.
As for Elton John, I remember ‘Can You Feel’ being staples on their national AC “playlist” and Delilah, so those could be significant factors in its airplay if it’s still in the rotation. Elton’s most recent solo somewhat hit I believe was “Looking Up” in 2016, which peaked at #12 on AC. It wasn’t a bad track, but almost seemed like one of those semi-“obligatory” plays, and it fell off the air by 2018 which is to be expected from an artist with such a massive, successful back catalog. He might have done slightly better in the current AC climate where we don’t have almost every CHR #1 crossing over to an AC smash and stations are playing fewer currents.
