Ask HN: Sorting Tool for music

I didn't know how long to make the title and I haven't been able to find the right keywords for searching on my own.

Is there a tool that can take a list of say 1000 (any number) of songs and create a playlist that is limited by length?

Example: I have 1k songs and I want 5 playlists of 30 minutes length each (non-repeating songs probably). Is it too complicated? What if other parameters were added (genre, min/max length per song) [thinking on this that would just decrease the pool of available tracks to search so it should make it easier I think]?

It reminds me of https://en.wikipedia.org/wiki/Travelling_salesman_problem but maybe there is a way I'm over-complicating this all.
