Spotify and others like it are great ways to hear new stuff too. I usually need to keep something around to tell me what's playing if I like it.
I kinda like the MTV stuff because you're likely to hear several songs or maybe even a whole concert. Like tonight, David Gilmour's concert at Royal Albert Hall is playing. Being a Pink Floyd fan, it's a great listen. Plus, Graham Nash and David Crosby are guest performers.
I never knew Gilmour had received a lifetime ban from the venue after a concert in 1969...it didn't last long, just 8 months.
