Not quite... I want to have a view of filtered tracks - according to my defined rules - but not necessarily a playlist.
If I've got a filter set to display e.g. old tracks, and this filter has a few rules set within it; I may want to then create another filter - adding more tracks to but based on criteria in another filter.
Also, a slight aside, I'm trying to set a filter just for dance music, but it doesn't seem to be working - what isn't working - I'm getting 0 results?
