Maybe off topic of engineering - but you all are radio guys. We use to air American Top 40 with Casey Kasem. I know that show is still on the air - now hosted by Ryan Seacrest. We will soon pick up a new top 40 countdown show but was wondering which is best. I know that's a matter of opinion. Also curious - which Top 40 Countdown Show (or Hot AC) program is the most listened to or most popular these days.
