a suggestion to wide up the playlist limits of cantata, each time I wish to "Play Now" all my music, this message appears:
MPD ha informado del siguiente fallo: Playlist is too large

seems limit is about 16384 tracks

That is a question for upstream, ask the MPD/Cantata devs why they set a limit and if they are willing to raise that limit.

indeed the issue seems to be fixed, there is no more messages and pauses with the playlist, Thanks!
