I do.. At home I listen to Liveatc.net, on the road to/from work I listen to ATC on my radio scanner, rather than local radio stations where they have tons of commercials..
Well, ATC don't carry any commercials other than the name of the flight carrier.
I also listen to ATCs while I am working, for some reason, I feel more concentrated at work while listening to them.
And yes, my wife don't appreciate that at all..
