MusicBee (Win) and Musicolet (Android) offer me an ad-free experience for free. I'm used to playing music locally, because streaming used to be unreliable and limited in catalogue. It may have improved, but I'm not willing to jump, because the default Spotify experience is so piss-poor.

For discovering new music I use last.fm, Bandcamp, and YouTube (with adblocker).

I tried to do what he said here, but I must've made a mistake because I can't repeat it
even if what he said doesn't make sense, I stumbled upon something else
// numbers repeat every
// 3 items - 7, 14, 21, 28, 35
// 4 items - 15, 30, 45, 60, 75
// 5 items - 21, 42, 63, 84, 105, 126
// 6 items - 21, 42, 63, 84, 105, 126, 147
// 7 items - 127, 254, 381
why is the "step" at wich the items return to the original the same for 5 and 6 items?
const arr = [100, 200, 300, 400, 500] // add/subtract items in this line
