your ideas on this perplexing matter are wanted

There are times when I'm brimming with ideas as to what to put in this blog. When I'm away from the pc, I come across something...or some thought pops into my head...and I say, "Oh, that would be great for rantsnraves!" Then later on as I log onto blogger, I go, "What was that thing I was going to tackle here??"

Here is one of those perplexing questions that had been nagging me for some time now which I had planned to post here, but which ended up in the "ano na nga ba yung isusulat ko sa blog ko?!" assortment:

Bakit ang lakas magpatugtog ng radyo ng mga drivers, lalo na habang naglilinis ng kotse?

From time to time, I have to contend with this -- our next-door neighbor has an open garage, and the driver has a penchant for leaving the utility vehicle's windows open, jukebox music streaming from inside. I wouldn't say that the stereo system is of the sophisticated kind, and I do hear the driver making like Aiza Seguerra or Ogie Alcasid at the top of his lungs once in a while.

Then there's our neighbor across the street, whose driver gives the family SUV a good washing outside their gate at least twice a week -- accompanying the sunrise. He, too, relishes the sound of ditties keeping him company as he works the chamois (sometimes ballads, sometimes techno). And his is a basag broadcast of the day's playlist at a volume level that enables me to listen from our dining table.

Then at the street corner nearest our house is a queue of tricycles, and quite a few of them sport boomboxes. If your tricycle had a boombox, would you keep it a secret? Noooo. You'd let everyone be aware just what your speaker can do!

I do know that in most exclusive villages, policies regarding music broadcasts from any resident are strictly enforced. Ours is not an exclusive village; still, I believe that policy or no policy, a person ought to consider the peace and quiet that others relish and which he may be shattering before he pumps up the volume. But then, people are different so I'll let the "ought/should" angle of the matter go for now.

My question is, what's the reason behind these people's preference for playing music so loudly when a) the sound is basag, and, b) they're not in a karaoke place?

Is it out of generosity ("para naman marinig ng mga iba, yung mga walang radyo")? Are they KSP ("lakasan ko nga para mapansin ako")? Is it an expression of rebelliousness ("pag mas malakas, mas maraming maiistorbo, hehe")?

Your theories please. =)

Thanks!
