I can understand wanting to play music loud. But doing it such that people in their residences are subjected to it is plain disrespectful and anyone who wilfully does it shouldn't be so shameless. You want to blast it on the freeway, fine, in a non-residential area, fine too (although if I happen to be in the same area I'll probably still think you're trashy and have bad taste in music). But don't park your ass on an otherwise quiet street with your windows down and blast it. Yes, wow, your system is so loud and your subs so expansive, you must have a penis of similarly epic size.
There's a time and a place...it's not outside my window at 2 AM.
