So in all the listing of favorite music player apps, I'm hoping forumites can help me out. 
I recently moved from an iPhone to the Galaxy S ii with T-Mobile. Things are great, except for my issues with the music player.  I'm looking for a music/podcast/audiobook player.
Obviously (see this thread...) There are a lot of great choices out there, and I've tested some, but still find myself  looking for "the right one".
What I want in a player is:
1.	Have a separate category for Podcasts ? Some, like Winamp, put the Podcasts and audiobooks in with 
        the music.  DoubleTwist does this right, but see below.
2.	Have a separate category for audiobooks ? see above.
3.	Play podcasts in order, and go to the next one when one is finished (DoubleTwist just restarts playing
        the same episode?Why?)
4.	Play *.m4b format audiobooks (I have a lot in that format already?and it's the only one I know of that 
        allows for picking up where I left off).
5.	Since I have been using itunes for a long time, and it is integrated into my ecosystem at home (Apple 
        TV, Airport Express) built-in iTunes syncing would be great, but I think I can utilize other tools (like 
        iSyncr or the DoubleTwist AirSync) for that.
6.	Of course, the app should also play music, and allow to sort by Artists/Album/Genre?but so far ALL of
        players seem to do that.
Of course, any suggestions for other features would be welcome?I'm sure there are tricks and ideas that I haven't thought of. 
I suppose if I had to, I'd settle for a separate Podcast/audiobook player, but I would like to have it all in one package.  no need to switch apps when i want to go to music from a podcast or vice-versa.
Thanks for the help!
