Yeah I'd agree that XRock does sound better, at least overnight when I listen to them. Whether it helps with overall numbers is another story. Time will tell.
I have a bigger issue with Anchorage radio. Last night I was listening to from about 1am to around 5am, just flipping around the dial while reading a book and net-surfing. During that 4-hour block that inane and way overplayed song "Hey There Delilah" by the Plain White T's aired on 92.1, 98.9, 101.3, 102.1 and 103.1. Daughtry's "Home" aired on 4 of those 5 stations (at least I didn't hear them on 92.1 last night). Many other songs air on 3, 4, or 5 of the area's stations sometimes within a few hours of each other. This shouldn't be happening. When listeners get the same music on as many as 5 stations in the same market, there's never a reason to settle on a favorite station, and the stations themselves lose all their identity. I realize there are some songs that must get more airtime than others, and stations are going to play the hits and not the lesser known tracks. But here we have 5 stations with different formats playing a lot of the same thing. This may explain why Bob is doing as well as it is - the competition is airing the same thing they are, so no one is leaving them for a better station. There just aren't any better stations (and that's most definitely not a compliment to Bob).
XRock, to their credit, is breaking away from that and, I think, they are really building an identity for themselves. They were sorta drifting there for a while, playing stuff I could hear elsewhere, but in recent weeks they've really improved.
Sat radio does very well because they offer narrow-themed stations, giving listeners specific choices among over 100 different formats. You tune to the 80s channel and you know you're not gonna hear Britany Spears. You tune to modern rock and you know you're not gonna get John Denver. I had XM until I got to AK (the freekin mountains block my signal too much to continue paying for it), and I tuned in to maybe 5 of the 100 or so stations on a regular basis. Some said I was wasting money on just 5 channels, but I say I was getting exactly what I wanted and nothing more (or less). I think there's a good lesson to be learned there for terrestrial radio.
