This DJ deserves credit for honesty, if nothing else, in this situation: Earlier this week, I heard an out-of-town DJ say he was about to play a song by a band a listener requested. He admitted it wasn't the song that listener requested. He said he was going to substitute his song choice for the listener's "because I just like this song so much more."
As much as I like the song the DJ chose, I kept thinking, "That's not how requests are generally handled." I wonder if, in the future, he'll say on-air, "Feel free to request a song. I'll play it as long as your taste aligns with mine."
