Here in Calgary, the Fuel 90.3 station seems to have a tie in with iTunes. They have a 'New Music Tuesday' with so and so. They tell you to go get iTunes and they say what the new releases are and what you should watch for. They have been pumping it pretty hard too.

Any other stations doing this? Tie in with Apple??

A bunch of stations in Toronto appear to be doing this as well, including Q107. It's just advertising, it seems. Or perhaps somebody made a bet about how often "iTunes" could be mentioned on air.
