I thought the quality from play music was sub-par with my X10s. Neutron>>>>>Play Music. 320 kbps MP3s sounded almost fuzzy, clearly missing more extension on both ends, subpar presentation elements. Also Play Music seems to have a hard time with FLAC, doing a bit of stuttering, which is about 80% of my regular music diet, and the only thing that sounded decent coming from Play Music. And I know it's not my connection; I'm a T-Mobile employee so I don't get throttled, and I ran SpeedTest.net at 12 mbps down in the same place. Conclusion: Play Music still sucks. Spotify is a better streaming solution IME; 320 kbps sounds fine if you have Premium.
It's really, really unfortunate that this phone has no expandable storage. This is a trend that I hope to see righted at some point in the Nexus phones. It's really quite a shame that Google touts the nexus implicitly as freeing you from carrier bonds, when in reality it only strengthens your dependence upon them. I will maintain that this is hypocrisy until I see SD cards or at LEAST a 32GB model of a Nexus phone. I could fill 64 easily.
I have to say, though, that is my only real complaint about the N4. I would have liked a slightly more rounded bezel, and a curved display like the GNex, but that's nitpicking for sure. LG definitely tops Samsung in build quality and general hardware (loved my G2x), and uses more-fair Korean labor instead of Chinese slave labor. I refuse to touch anything produced by Foxconn or their affiliates.
how about poweramp or player pro?
