I don’t have a problem with it playing a song way out of nowhere, but what if does do is play the same like 20 songs over and over and over when I let it try to recommend things. Like the songs it picks are decent recommendations but damn could I have something different?

And while we’re venting, its recommended album feed for me is surprisingly good, except that half the things it recommends are singles releases. I don’t want to see those please let me just se albums…

At least they fixed the bug where “repeat album” would constantly turn itself on.

It’s not useless, it removes a lot of the tracking cookies and such and sponsored links loaded with telemetry. Theoretically you can also get the benefits of anonymity if you proxy through Tor or a VPN, which I originally tried to do but turns out Google at least blocks requests from Tor and at least the VPN endpoint I have and probably most of them. Google or whatever upstream SE can still track you by IP when you self host, but its tracking is going to much less without the extra telemetry cookies and tracking code it gets when you use Google results directly.

But yes, practically you either have to trust the instance you’re using to some extent or give up some of the anonymity. I opted to self host and would recommend the same over using a public instance if you can, personally. And if privacy is your biggest concern, only use upstream search providers that are (or rather, claim to be) more privacy respecting like DDG or Qwant. My main use case is primarily as a better frontend to search without junk sponsored results and privacy is more of a secondary benefit.

FWIW, they have a pretty detailed discussion on why they recommend self-hosting here.

I’ve always gotten the impression it was mostly intended to be self hosted. I’ve self hosted it for something like a couple years now, runs like a clock. It still strips out tracking and advertising, even if you don’t get the crowd anonymity of a public instance.
