Unless I am entirely missing something (which is certainly possible), I can't seem to easily create a playlist based on all music in a *folder* using the stock music player. I have to select each song one-by-one out of a list of all my songs on the phone, which is tedious and time-consuming. If I'm missing it, please let me know. In the meantime, I downloaded a very basic player called "Player." It does allow you to create playlists based on all music in a folder. When you navigate to a music folder and select some or all of the music in the folder to play, "Player" creates a temporary playlist with all of the music selected. NOTE: A message pops up saying ONE song has been added to the playlist, but this is incorrect (unless you've only selected one to play). If you've chosen multiple or all of the songs in the folder to play, it actually creates the playlist with all the selected songs in it. Since the playlist created is a temporary playlist, so you must go into the "playlist" area to rename it to what you want. If you don't, then the next time you select a folder to play music from, it will likely overwrite the first temporary playlist with the new one. It's actually very, very easy (much easier than scrolling through to select each song). The playlists created by "Player" automatically show up in the stock music player as well and can be played there. One negative to "Player" is that it appears to display the wrong album art. If that's a big deal, then simply revert to the stock player and run your playlists from there. I realize there are other music apps in the markets, so this wouldn't apply if you prefer one of those, obviously.
