Lumin Ap on Lumin players - not so good?

My experience has been you can add music to the music playing in the left panel.   You can add the whole album by press selecting the album or single tap music change view for all the songs and select those you want to add.  If you add using the arrow on top of the file icon, that selection immediately plays whether individual song(s) or whole album.  

No seems u have to select songs one at a time.  Will not play fullalbum

horrible

You have read the Lumin Online Manual, especially sections 5 and 6 as it relates to Lumin App, correct?   I suggest you actually use the manual for each shown subsection with your unit to experience what happens.  

I suspect you may want to specifically try changing your Operation settings for Tap on Song List and Tap to Play in Playlist in Settings for Lumin App.  As I noted prior, I can add whole album to left side playlist. I have mine set to Double Tap and Play Later for Tap on Song List.

You can play more than one song at a time. RTFM.

I have had 4 different Lumin Players over the last 7 years and love the Lumin App.  It is easy to use.
