Sitting in my garden and you can guarantee someone will start playing music, we surround a school field so its a lot of back gardens concentrated in one place. I can't complain that it's rave or too loud, its eclectic and not full blast but it disturbs the peace, I can hear the exact song and it reaches me at the volume I would have in my own garden as background noise.
I am not a big music lover, find it over stimulating maybe and jarring when the music doesnt match my mood.
I understand people want to enjoy their gardens on a nice day but if you want music that badly, wear earphones. I want to hear the outside - trees blowing, regular daytime noise and birds, not your music!
