It's a safety hazard... but man doesn't music sound great when you're flying down the street? I usually have it on 1/2 to 3/4 volume level. I can usually hear if a car is coming up behind me (unless its a prius or something), but I wouldn't be able to notice if my bb was making weird noises.
For those of you who think its irresponsible, share your thoughts. And for the other half of you who do listen to their ipods, what are you guys listen to?
I've been vibing on Nujabes. On the indie-rock side of things, I've been listening to the shout out louds alot.
