Maybe. That assumes people pick their favorite songs based on the year of release. As we've seen, all it takes is for a TV show to use an obscure song from the 80s, and it instantly becomes a hit everywhere. So it's possible, with new generations being exposed to music from the 80s, that those songs may recirculate to a new audience. A couple of weeks ago a founding member of Lynyrd Skynyrd died. But the band's hit Sweet Home Alabama continues to test well with young audiences, and the band continues to tour off their 40 year old songs.
