Welp I finished the 3rd Annihilation audiobook today/tonight on my drive. Still a little confused about what exactly was going on but I think maybe that's the point.
Saw someone mention World War Z so I went hunting for how I can listen to that one. Turns out it's not available as part of the Spotify Premium audiobooks and there was no option I could find besides buying it sooooo I may have hit the high seas. I could only find a version of the cool 2013 edition in like 92 WAV files and every 10th had overlapping parts so I stayed up late merging them all into 1 big MP3 and getting rid of the overlaps so it's nice and smooth. Found a great Audiobook player for Android which has Android Auto support called Smart Audiobook Player and was more than happy to right away pay the $3.29 or whatever it was for the full version after giving it a quick try.
It's a fantastic app from what I can see. It's how apps should be.. like they used to be before everyone started charging subscription fees.
