Must be surely something like this. Simply have no idea what is the simplest to implement in Mixx.
Still trying to have this compiling in Eclipse under W10.
May be that once we are able to do this we can feed this to a player and see how is difficult to modify one of the two (i.e. Mixx or the player). Surely not necessary to stitch to pure XSPF output.
