Can you guys recommend an Android phone that is great as a music player?

I know most would suggest to get an mp3 player to accommodate my phone, however, I don't want to keep two devices. Especially, when to work, I just normally have my phone in my pants and I don't carry anything else (I don't want to put another device in either of my pants pockets).

What I;m looking for is great music quality and a high storage - like the iphone 5 64gb. Is there an android equivalent?
