Android phones and music

[InversneckieDob]

Lookin' for some tech input from those less Luddite than me.

I'm increasingly eschewing my ipod in favour of the music I'm storing on my mobby, listening to same via bluetooth technology.

I've got one of those micro SD cards therein, upon which my contemporary beats are stored.
I tend to just drag and drop from my itunes library onto the card and they appear, as if by magic, in my Google Play listing.

This works well enough, however in my perennial quest for self improvement, are there any better apps than yer basic Google Play for playing sounds?

I'm due a mobby upgrade, so I'll be looking for mair memory (and a better capacity for utilising a bigger micro SD card) but that's a separate journey.

Crivens it's great what they can do these days..........I mind when a Sony Walkman was cutting edge.
