Audio [Q] Using the Nexus 4 as a dedicated music/podcasts/radio device

So, over the weekend I got an LG G2 as my N4's battery has become less than stellar and I could buy the G2 super cheap. So now I have a spare N4.

I got thinking and I'd like to turn it into my music/radio/podcasts device.

So my question is, are there any Roms good for this or must have mods to help me along the way?

I'll be using spotify's offline mode + pocketcasts downloads so battery shouldn't be an issue.

Many thanks
