Most misguided broadcast concept in recent memory has to be the all-Led Zeppelin radio station in Clearwater, Fla. Kicking off its promotion on New Year's Day by playing "Stairway to Heaven" 181 times in a row, the format took off like, well, a lead balloon.
Biggest drawback to the all-Zeppelin policy was that there simply wasn't enough music to make it fly. In its 12-year history, the band produced 10 albums which run for a grand total of just six hours and 27 minutes. After 11 days, programmers decided to add the Rolling Stones, Pink Floyd and ZZ Top to the playlist at audience request.
