Samsung Galaxy S II :: Playing Music Directly From "files" Folder And External Sd Card?

I have an SIII but no one seems to be viewing those forums so I thought I would ask here. I've always stored my music in folders sorted by artist and never bothered with tagging as long as the file names started with numbers. I have over 300 gigs in music so I'm not about to start tagging now. my 32 gig sd card has 4500 music files.The music player doesn't play nice with my sorting - artist view winds up showing the same artists 10 times or sorts out compiltation albums while folder view has every single album (300-400 or so) sorted alphabetically.

I would like to go into the external sd card and play directly from there. I can do that, but only a single track will play and you can't use any other apps or browse when the track plays. Am I stupid or something?This is the main reason why I've always used Cowon music players or my sansa clip, I can simply go into folders and play. I have media monkey and love it but even there I use the folder directory.
