Gee... maybe it's a regional thing, but having traveled for aliving most of my life, I've never heard that use of the word...
Additionally, haven't really heard the use of 'telly' anywhere in the U.S.... at least not unselfconciously... We all know people that use (pardon the expression) foreign phrases to impress people all the time...
What's the context in the song? Most common expression here is still the ancient 'T.V.'...
I'd say greedyfly is correct as I doubt very much that the song to which you refer is about leaving a nightclub so as to get back to the house in time for Neighbours or Home and Away.
I have not heard this at all and I am in US and a High school teacher. If classes were in session, I could find out right away. These kids and their new-fangled language....LOL
