Using today's hit music or the music of the '80s? With today's music, a bright, personality-heavy approach is going to seem excessively talky to its target audience, which by and large wants the DJ to shut up. If you're talking about a full-blown recreation of Zoo or Hot Hits -- "Easy Lover" into "We Built This City" into "Rhythm of the Night" with jingles and shouts and fast talking DJs, remember that most of the songs you're going to be playing will be at least 35 years old, which means your average listener is going to be 50+. Heck, I'm 65 and I'd listen to that format! The clock is ticking on an '80s format even as a quick fix.
