Some good suggestions here - thanks guys.Ultra Nate - I remember that song well (and liked it!). I remember in particular the heavy bass line to that song, which was sort of a melody in its own right. The bass line to the songs that my anti-social neighbours listen to, however, is more of a "thud thud thud". They seem to like 'novelty' music that involves a 'jumpy' sort of drum beat. In practice, it sounds like someone pounding at the walls and floorboards about 2 times every 3 seconds. Every now and then there will be a gap of silence for about 15 seconds - just long enough to build up the anticipation in my own mind and keep me completely on edge whilst I wait for the next round of "thud thud thud" to start.Polish Plumber - It's not that I don't like Europop. In fact, I quite like a lot of it, including many tracks from the 90's, e.g. the German artist Westbam's 'Celebration Generation', Ultra Nate, Capella, etc. However, my neighbours seem to prefer the more modern variety of Europop which introduces more of a RnB element than the techno/dance that I prefer. I can't stand RnB-inspired Europop. Or remixes of Whigfield when they're played on loop for 5 days in a row (Mon-Fri) when I'm trying to work. It is very distracting.Stud - Good suggestion, however I imagine his 'partner' (they have different surnames) may already have an STD. She is that 'sort'.Mars a Day - I have to admit I've been tempted to take up your first suggestion, i.e. resorting to direct ation. The problem is that society seems to have a warped idea of who is really the 'victim' in these kinds of situations.taxrebate - More good practical suggestions. I'll certainly look into noise cancelling headphones. But I can't believe it's come to this.aa - Another good suggestion that would work with any rational, cooperative neighbour. The problem is, I think he's half-deaf or something. He doesn't understand that even a fairly quiet rumble can be quite loud and distracting when it's played 20 hours per day. He thinks I'm being unreasonable in asking him to turn it down, to the point that he has lied about turning off his subwoofer presumably because, idiot that he is, he thinks it's all in my mind and I won't be able to tell the difference.At this rate I'm going to have to move!
