I've been thinking the same thing, although the changes started before the full transition of 100.5 to MyFM. I don't see any possible way that MyFM is going to last much longer, and I feel like this week could be the end for them (Christmas music by Saturday probably, they could hold out until sometime next week though). When The Fox was on 100.5, they were dealing with competition from WLRS at 105.1, which despite everybody saying nobody has ever listened to 105.1, the early-to-mid 2000s WLRS was perhaps the most successful period for 105.1, and they did well enough to steal a significant audience away from The Fox. They're all alone now. Something will happen to 100.5 much sooner than later, because MyFM has been a HUGE flop. Will it be The Fox again? Who knows, but they don't have a whole lot of options.
Then again, how many times did 100.5 go Gen X-Mas, with everybody on here speculating that there was no way they were coming back... yet they did?
