That's fine. Your list, your rules.
But you're still talking out of both sides of your mouth. As
@Osaurus posted a bit ago, some of your arguments seem to be retconning from a 2020 perspective and others are "in the moment". I can tell you with 100% certainty that Prince's songs off of
1999 and
Purple Rain were played on the alt/new wave station in Washington, DC.
In any case, fun thread. Thanks for the effort.
I've slowly been building my "Top 2,020 Songs Of The 1970s" list for a thread here. At least I won't have to defend whether I'm breaking some basic rule, since inclusion is based on fact (the song was released in the '70s). I'll get hammered on my exclusions, but that won't surprise me based on this board's demographic.
