mess when adding to the playlist tail

[one-dash]

Currently most of the players don't have a 'add after current' option for adding tracks after currently playing, they add to playlist end instead. This way tracks already added by autoplay will be 'skipped' and so badly rated. How can we address this without modifying third-party players?

I know, this one is not that easy, but here's the problem, I want to pursue two things:

1. I want to add a 'custom' track into the playlist.
2. I want 'custom' track to play after current gets finished.
3. I do not want to affect the playlist and ratings of the tracks currently added by autoplay.

I will look into that, but I feel it is more the client's job than mine. Note that mpc has insert.
