That's a feature. Artistry was a failing industry in the era of the boombox; friends and family would steal the hard work -- performances -- of artists in the streets of our nations. Handheld devices have come a long way of protecting the consumer, from the likes of the MPAA, and the artists, from those of us stealing their live performances.

Plus, one looks rather moronic carrying his smartphone on top of a shoulder and walking n a funky style :P

It already does a pretty good job at annoying me in the bus with other people's dance/rap "music"

the new breed of smartphones with their tiny mono speakers on the back do a poor job at it.

a lot of old style smartphones from nokia had such unheard today feature as builtin stereo speakers. but I've even seen low-range handsets used as boomboxes in the developing world.
