Another vote for Symfonie. It has another upside that is does not use tracker. For Symfonie, directory = album. Which suits my use perfectly, I find all that sorting by metadata confusing. So if you ditch both osso-mediaplayer and OMP and switch to Symfonie then you can ditch tracker too and save a lot of memory and CPU cycles.

@rotoflex, do you need Ogg support installed to play .ogg with Symfonie? I don't have any .ogg files to try it out.
