I loaded both of those yesterday. The apps are pretty ugly. I don't think I'd use either of those. VLC for Android (beta) works with AA. It has a good layout and there are no adds either. The problem with VLC is it doesn't seem to work with Assistant. You can't say "play Elvis on VLC".

It seems like they all have their issues at the moment. I'm using Rocket Player now because the album art looks better in the AA app. I actually prefer to use Spotify Premium since I have an unlimited data plan, it streams at 320kps. My iTunes backup sounds terrible in comparison to Spotify Extreme quality. I use android assistant with Spotify all the time so I would miss that feature,
My favorite for local music is Sony Music. It takes a little work to get it installed and working though. First you have to find the app on XDA that has been altered to not check your build.prop for a sony device (there are several). I'm using the app from here:
Then the problem is Android Auto will not work with a sideloaded app. To fix that you need ADB shell:
adb push Sonymusic.apk /sdcard/Download/Sonymusic.apk
adb shell pm install -i "com.android.vending" -r /sdcard/Download/Sonymusic.apk
adb shell rm /sdcard/Download/Sonymusic.apk
Skip the first command if its already on your phone. You need to use the phones package installer for this, so the apk needs to be on the phone somehow. Change the file paths and file names to suit your install.
This works with other sideloaded apps if you're into that sort of thing (Pandora, Spotify, etc) ahem
It's 2 min of work from a computer, but it's the best experience for me. I tried every Android Auto compatible music player I could find. Sony did it right IMO.
