Practical to use a Samsung Galaxy as my music player?

Heyo, I'm sick of having both a "dumb" phone and a rather bulky MP3 player in my pockets.

Want to consolidate them both into one so I'm finally getting a smartphone.

Question is, is the Galaxy S3 practical as an MP3 player? Is the sound good, can it organise by genre/track/artist/album, make playlists, do a random shuffle, etc? Is the battery life ok, or does it drain quickly while playing music? How does the phone work while I'm listening to music, will the music cut out if someone rings or will it play over the music (or not ring at all :P)?

I've read lots of reviews but they're all very general and no one really mentions the music capabilities specifically.

Thanks for your help :)

well it's android so there's plenty of options when it comes to music playing software.

However it will drain your battery faster, not sure how much on that phone though. I'd assume it will stop music when you get called etc

The DAC in the S3 (and the note 2, for that matter) is well above standard quality. The s3 would be a perfectly competent music player, and battery shouldn't be an issue.
