MP3 player recommendation please

I know that there are loads around but without testing each one it is difficult and those I have tried don;t do what I want.

Essentially I need to :
a. define as source folder on the SD card which contains the mp3 files and it should always default to that.
b. Play those files in order.
c. Remember if I stop half way through so that I can, later, continue from that point.
d. Have the usual controls ; Play, stop , next , last, and to be able to drag the time to advance within a single playback.

Thanks in advance

A quick test suggests it does.t do it for me.

E.g how do you define the default folder?
