IIRC those are only 256 kbps. I get that MP3 is a lossy format, but still, they could at the very least offer 320 kbps. I was under the impression Amazon wasn't short on server space.
Hell, I'd even take $5/600. 300 is just ridiculously low. I like the service, mind you, but really can't justify paying $10/m (+ tax now) for it.
I should have jumped on the Neeva train when I had the chance. It was 50€/y. The results weren't as good as Kagi's, though. But anyway, Neeva's dead now.
You can install "Sink it for Reddit" to remove that obnoxious "pretty please install our app." banner. It also does other stuff to make their mobile website not as bad, but it still isn't a great experience.
