This x100 also. I cannot stress how important this is. There is NO PLAYER in the market that has this feature and able to perform a folder list play.
It is such a missing feature, that I have at least around 10 friends of mine asking if I know a software that does it, and I'm actually thinking of coding a simple folder player that does this.
If Poweramp does not reply to this question, is there anyone out there interested in co-developing or helping to develop such a player? Contact me at david.afonso@gmail.com
