That's pretty much the only station I listen to. I used to be a WMMR guy, but those times have come and gone. 104.5 all the way.
Nope, they've never stopped into 104.5, as it's a pretty new station (4 years i believe). However, they have played WMMR (to my knowledge), and played Y100 back in the day (which is when i discovered them, promoting make yourself)
