Where we live we can hear the music from the beach clearly enough to identify the song and the artist - and we're not beachfront. On the other side of us is a colmado, enough said about that. The worst was the Evangelical Church, near the colmado, I swear they used to compete to see who could make the loudest music, the church often won, the downside being some of their "soloists" were less than professional. They would sing at the top of their lungs, with music, until 1 a.m. some nights.
Finally the junta de vecinos had enough - we don't have police here that we can call. A group confronted the church, and an agreement was made to cut the music early - 10 p.m. I think. I never hear them anymore. The colmado still plays music, but since that time it's bearable, all we need to do is turn on our Lasko stand-up fan, and that is enough noise to cover the music and let us sleep.
We also have a neighbor somewhere behind us, whose wife left him, and he plays the same CDs over and over, on top volume, singing along with them, for hours on end. Definitely aided by Brugal.
Nothing can be done about the beach music, but we've often wondered how the folks living closer can stand it - maybe they're half deaf already?
