Same! I have yet to hear MTN, and i heard Y&I a grand total of twice!
Radio 1 are playing it, hopefully after XFactor it should shoot up iTunes, and other stations will get on board too.
It did get played at a bar/club I went to last night, though. Heavy Metal Lover always gets played, but I was happy to see that MTN got a spin as well. We Found Love was the definite hit of the night, though.
