You know it is very bad form to play loud music on a lake from a boat. It really carries over water, and the rest of us don't want to hear it.
We had a lovely lake home in Northern MN for 20 years. People drifting round the lake playing loud music were are real menace. I would go out to them and remind them of the noise ordinances, and actually give them a pretty good dressing down. Lakes are for peace and quiet and NOT music.
I've had to build ski arches and towers around speakers (usually some kind of oversized 'cannon' of a speaker). Whole time I was thinking about the importance of stealth when fishing, which is most of the reason I am there, personally. If they didn't make excellent IEMs and headphones, then there would be more room for an excuse, if one has to listen loudly, and especially with genres of music that can be considered 'controversial,' which many are, beyond that of a whisper.
There's a time and place for it, but I personally just don't enjoy music so much when it annoys someone else. Is why my loud system is indoors, and I am mindful in the wee hrs of who might be hearing it.
There are often times, long spells in-between that I can finally get on the water. Thankfully I have places to get away from the yahoos because Tampa Bay is large enough. Not so much on lakes though. Best time to fish is on Sundays, because the same mouth-breathers that eff it up for others, are TV sports fans as well, at least during football season. Super Bowl Sunday, I can almost guarantee having the bay mostly to myself, or as far as I can see, most of the time.
Best times on the lakes here is normal weekdays. Only people that can really be found out there then is retirees and they well understand the "shut-up and fish" rule. We were there likely playing 'hooky' from work, and we damn sure didn't want to rile anyone.
