The technology exists within NexGen and/or prophet to do this...but usually only during spot blocks.

This isn't completely unheard of. TV and Radio Stations will sometimes use a digital device to clip out "redundant" frames of video or audio to get a few seconds more for commercials.

I've heard songs on the radio sped up before also on Clear Channel stations in my area (Pittsburgh). I believe it was on their KISS-FM (Top 40) station.

It's probably just the drugs.

this may sound like a silly question, but why do people listen to the radio? i'm against clearchannel as much as the next guy, but commercial radio in general is a big seething roaring mass of excrement. either you hate the songs they're playing over and over, or they play your favorite song and somehow mess it up.

I guarantee they were sped up. They do that to get more ad time in.

Just like when they say a film has been "edited to run in the time allotted". Same thing. They're all sped up and shortened.

At some point in the not-too-distant future there will be absolutely no art nor entertainment left, just advertising.
