If there's no setting on that app, yes, you need an app with a setting to turn off shuffle and run by some order - song name, artist, date, etc. ["in order (1,2, 3, etc.)" in a computer (and the phone is a computer) is meaningless - it means the order that the phone doesn't give it. the order in which files are is somewhat related to the order in which they were put on the phone - but if there were any blank slots in the directory (from previous files having been deleted), they'd go into those slots first, so the songs you might be wanting to play may be in "an order" that includes other songs. Never depends on files being stored in any particular order on a computer - they're not.]
