The sound of *some* windchimes is lovely. Others, not so much. I have a nice one that was a gift. However, I live in a neighborhood where all the houses are very, very close together and most are multi-family homes. The backyards are small and nearly every home has a porch or balcony in the back. The potential to really annoy the neighbors with a windchime are just too great, so I hang mine in the kitchen window, so I can at least look at it.
Friends of mine have a very nice apartment in a building where each apartment has a balcony. Their neighbors have, at last count, 30 windchimes on their balcony. I'm sure some of them have a pretty sound, but when all of them are chiming at once, it is a cacophony. My friends can't really use their balcony because of the noise.
When I'm visiting those friends, we try to come up with reasons why the neighbors have so very many windchimes. The current theory is that the MIL gave the bride a windchime as a wedding present. The bride hates windchimes, but hey, it's from her new MIL and she wants to have a good relationship with her, so the bride waxes very enthusiastic about the windchime and hangs it up. That, of course, is the kiss of death. The MIL spreads the word amongst the family that the dear bride LOVES windchimes. Since the husband's side of the family doesn't know the bride very well, they latch onto windchimes as a good gift. So the poor bride is inundated with windchimes, at least one at every possible gift-giving occasion. Stuck with the original lie she told her MIL, she is forced to enthusiastically every windchime that comes her way and hang it up on the balcony.
Either that, or the couple is hoping to drive all their neighbors out so that they will never have to hear any noise from any adjoining apartment. And in the meantime, the windchime noise blocks the footsteps of the upstairs neighbors.
