I'm trying to find a simple app that can take MP3 files, preferably from iCloud cache (the iPhone's local storage) and arrange them in a playlist.
VLC is supposed to be able to do this, but when I try to load the MP3 files in, it is hit-or-miss: sometimes I get duplicates, sometimes the MP3 doesn't get added to the playlist at all.
What would be a good iOS app for this? Preferably free but doesn't have to be.
