I don’t listen to audiobooks to know any good titles, but sites that sell book bundles also usually have audiobook bundles, so maybe they’re a good starting point for finding titles?

Also, if you use Spotify, I can presume you’re at least not overly against DRM, so maybe you’d be interested in Storytel? Came across it a while back and people seemed to talk well of it, apparently being a subscription-based streaming, but didn’t look for further info on it as I saw it is “DRM’d”.
