Does it download the actual music tracks from youtube-music, or does YouTube helpfully provide the video version of the music?
I’ve used a few downloaders and it seems these days that every music video is a whole “production” with 30 seconds of dialogue and intro before the actual music starts, or there’s background noise over the first dozen bars (because the artist is in a cafe or car park or on the train in the clip) and all of that is just a bit tedious when listening to the audio only.
The Maillard reaction (the browning process when frying/searing food) creates a few compounds suspected to cause cancer. So… eat a lot of steak, eat a lot of carcinogenic compounds.
