The reason why "Jack" is NOT getting big numbers is because it's a hodge podge format. Too much inconsistancy. What's needed is a CLASSIC HITS format. Not oldies, not classic rock. Classic Hits would play songs from the '60s and '70s that were genuine Top 40 hits. If the song peaked at #39, it would still get airplay. "Oldies" formats are too limited and Jack is like the 1950s & 1960s MOR format...a little bit of this and a little bit of that that pleases nobody.
