If you use Cityrail, you'll know what I mean

So today I was on the train and a lad starts playing music over the loudspeaker of his phone at full blast.

This attracted another lad from the opposite end of the carriage to walk over and say "Oi, hectic song. You reckon you could bluetooth it to me bro?"

They hit it off and next thing you know they're trading songs by DMX and Akon. "You like Tupac bro? I got a couple Tupac songs too if you wan'em. Here let me play it."
