Stock music sites

I've been a member of Artlist for a couple of years and testament to them they must be doing well because recently I have heard many other videos from production companies to global brands using the same music as I have on some of my content.

So I think it's time to look for another site to buy from because it seems to of saturated the market. Any other similar sites to them worth checking out?

I still have accounts on PremiumBeat and a couple of others but haven't needed to use them because of the content on Artlist.

In addition to what you have listed, we have used these sites below in the past (and still do):
Storyblocks www.storyblocks.com/audio
MusicBakery musicbakery.com
Audio Jungle audiojungle.net/?gclid=EAIaIQobChMI7Pzh3...xEAAYASAAEgJK_fD_BwE

Any thoughts on using SmartSound (SonicFire), Filmstro, or similar? They allow a lot of customization which adds more variability to the recordings.
