Hi!
So, I think I should start with what I actually wanted to create: a stereo without music effects, playing only one station, that won't make sims dance, and with an invisible recolor.
(At first, I actually wanted to make a rock that emits music, but I soon found that this is far beyond my non-existent skills).

The function of this object would be to get ambience sounds on community lots (like, bird sounds in a forest, for example), using the Maxis radio stations.
I cloned three of the community lot wall speakers, made them fully transparent because I couldn't figure out how to enable the design option, and I.. well, I deleted the pie menu strings and the music notes effect BHAV. It seems to work, I tested it with testingcheats and got no errors.

However, there are two things kind of bothering me. First, Sims can still dance to the music playing. I'm not sure how to change that. Maybe it's possible to disable whatever makes the game know that music is playing. I haven't seen autonomous dancers, but I haven't tested for long enough to be sure.
The second problem, which you can see in the screenshots, is that the non-existent texture of one of the speakers was glitching out (the New Age one). At first, there was rainbow colored checkers, and then it pulled some weird texture with letters, which was kind of scary. I don't understand why.

In my files, you might notice a green texture among the transparent ones (it's 8x8). I did that to make the invisible object easier to find: When zooming out, part of the texture starts glittering in green, but it's still hardly visible. Maybe this was what was causing the texture glitches on one of the speakers.

I apologize for the long text that was probably hard to read because I keep jumping between things.
What I would like you to do is check for any mistakes I made that might cause issues, and if you have any suggestions how I could improve my files, maybe slim down the size, I would appreciate that too.

I hope you guys don't feel like I'm stealing your time, but I seriously don't have any experience and I don't trust my own judgement enough to upload my project as it is.
Thank you for your time!

As no one has replied yet: Did I do anything wrong? I just want to know if my mod is safe to use, and if I made any obvious mistakes.
