It depends a bit on your operating system. But I suggest audacity as a cross-platform, easy to use, but powerful audio editor. As long as your song has a common section to loop from you should find this very easy to do.

~~Is there a way to easily just remove the negative space maybe?~~

That might be more of a podcast condense feature lol

When you open your file in audacity you can just select the dead air and delete it.

Like at the ends right? Not in between right?

Anywhere that results in the mix you want :)

For example I have looped the instrumental parts of songs in the past to create 'falling asleep' mixes.

Play with audacity a bit. You can basically treat a song like a text file and copy/paste/delete

And that is without even getting to the filters and other tools.
