ROCK N ROLL TUBE MAP

So last night I had a dream that I was living in a place called Rock Ciry and I guess the Underground looked somewhat like that:

The lines are named after the different rock genres and on the trains would blast out the finest tunes in rock music, while the walls would be paved with posters of the bands instead of ads.
I'd never get off the trian me thinks :D Just hopping from line to line, depending on my mood.What's your favourite one folks?
