I'm not sure we are talking about the same thing...

So I would be able to select a playlist,
and then select only a few of the songs in that playlist,
by number of stars for instance?

Yes--autoplaylist functionality is a high priority item on our to do list.

I would love a Playlist Browser on Android,
to sub-select songs by any tags...
within a selected Playlist !

Ratings, BPM etc
Just like in the Desktop version.

Will that be a future feature?
