Other comments are on the right track. You likely need to get your music tagged correctly. From memory, you want the Artist tag to be A feat. B, then the Album Artist tag to be A.
MusicBrainz Picard is great. Especially if your music comes from formally released albums. My issue was having lots of indie playlists/albums. I solved this by having Various Artists labelled in the Album Artist tag (I think).
Broadly speaking, you probably want some kind of relay either mechanically switched or electronically (e.g. with MOSFETs). Most people would prefer an electronic one as they won’t make a “clack” noise when turning on or off. Electronic may or may not be more expensive, it depends on the rating.
The key factor will be getting one that is rated to the voltage and current draw of the motor. If the motor is AC powered (e.g. 240V) and is rated at 1200W, then you will need a relay rated to 10A. Same thing goes for DC, just smaller numbers.
You should be able to find some kind of wireless relay on Amazon as well. There are plenty of WiFi ones I’m sure if you want to use an app. There’s probably also an assortment of radio ones if you want to use a fob key. The easiest would be to look for something that is a kind o “inline adaptor” so that you plug it between the power and the motor, and it powers itself.
The messaging bubble issue may seem silly, but could I not open the gates to more unified messaging in general? Like WhatsApp to Signal to iMessage? I would hope there is a greater scope than just the bubble.
It looks like they’ve beaten this record by a factor of ~3! From ~100um to 35um. What an advancement!
