The next version of Master Audio will have automatic support of the "Preload Audio Data" checkbox on Audio Clips that was added for Unity 5. This can be used as an alternative to Resource Files and saves on total audio memory used. Extremely beneficial for large playlists so that you don't use audio memory for all songs all the time!
As always you can find the latest info in our dev support forum http://darktonic.freeforums.net/ or in our Unity forum thread.
