Unfortunately, this thread could be a million miles long.
I can think of several songs from Bob Seger and the Silverbullet Band beyond Nite Moves, Against the Wind, Old Time Rock and Roll that are more deserving of air play than those songs.
Even Now is one them. The internet has been scrubbed of that song thanks to Seger being a hold out against streaming. One crappy promotional live video is all that exists on youtube. His iHeart, Spotify, and iTunes catalog is very limited.
But this also comes back to the RIAA. Radio stations have to pay a licensing fee to play the songs they do, dictated by the RIAA. (Why do you think the modern pop stations seem to only have like five songs in the playlist? Those are the songs the RIAA wants to promote and charge a minimum for as a result, those are the songs that get played ad nasium to the point that you've heard it ten times a day and get sick of it quickly. Even the supposed Top 40 stations don't play the entire top 40, maybe just ten.)
When a station has to play songs that bring in listeners and the ad revenue that goes with it, they aren't going to pay for the B-side of the single.
That being said, here's Even Now. A lot less polished than the studio version which came some years after this live version.
