I'm on Maximus HD, I clicked on it from the playstore and it started to download and install. (I cancelled it)
So I assume it is your ROM.
I've always thought the compatibility depends on kernel or on the hardware...
Well, I'm going to try ...
Just tried the Rom with the 3.4 kernel.
With a clean installation (I had another rom), it works fine at first time without any fix.
Now I have no more issues with Play Music as I had before with this rom.
But the battery life was very very short...
read the posts, its literally one page behind that someone ASKED THE SAME QUESTION!
you'll need to flash the apk separately.
here is a step by step in case you are "special"
1. download THIS
2. place in sd
3. boot into recovery
4. flash ...
settings, manage applications, then click on any application, move to sd button.
Ok, thank you! :)
And go on, you're doing a great job! ;)
