I know CHR stations repeat their music often. Traditionally, 93Q seems to be on about a 90-minute rotation, which I think we could all agree is about average. But last night, Monday 5/15, was a little less than stellar.Rihanna / Unfaithful played just before 8:45 PM, followed by Cascada / Everytime We Touch.Then, at about 9:05, yes, just over 20 minutes later, the same Cascada song played again, followed by the same Rihanna song. ??? Did someone sneak into Selector and toss the "Artist/Title Separation" rules out the window? Is someone asleep at the wheel? Anyone at Q don't believe me? Your on-air computers probably keep track of everything that plays -- go take a look, or even check Mediabase for independent verification.Maybe the 9PM hour plays were there because they were the vote winners for the Top 5 at 9, and they were inserted into the log after the rest of the day was already laid out. OK, but don't be lazy! Go back through the log and check for stuff like this!At the very least, Rick Roberts, as the DJ on-air and the last line of defense before the airwaves, should have had the common sense to pay attention to the log and realize "oh hey, two songs repeating in less than an hour... I should probably do something about that." Or maybe there's strict rules about changing the log, in which case I sympathize with Rick for having to deal with an MD and/or PD that made him look like an idiot there.Missing little details like those... is what will drive listeners to your competition, or worse yet, away from radio altogether, and over to iPods.Not slamming Q... I'd post the same post had I caught the same foolish error on any other station.
