Description

Fixes #5207

• Documentation. (If you've added a new command-line flag, for example, find the appropriate page under docs/ to describe it.)
• Changelog. (Add an entry to docs/changelog.rst to the bottom of one of the lists near the top of the document.)
• Tests. (Very much encouraged but not strictly required.)

Hi @arsaboo, I've actually looked at this earlier and wanted to fix this issue for once and all.

I looked into the algorithm that beets uses for matching and I replaced it with one that is faster and uses less resources. This means beets should be able to handle candidates of any size. Let me find this work and submit a PR, then you could potentially test it?

@snejus that's awesome. Closing this PR in favor of the other one.
