Greasy Fork

Whenever I hit the button, it adds the first two or one song "up next" on the queue, but then skips them and they're not included again in the queue

I'll look into it, thanks for reporting. Sorry I only got around to it now, GreasyFork didn't send me an email.

I found the issue, I needed to increase one of the delays a small amount. I'll push an update in a second.

Here is a more technical writeup of what's happening. To reset the queue, the script clicks the second song, then the first song, then pauses. I increased the delay between clicking the first song and clicking the second song from 50ms to 150ms, since it was failing to click the first song. This will cause more songs to play a bit when clicking the button.
