First, thank you - all of you - for offering advice and help. I really do appreciate it.
I'm at work now, so I won't be able to send a screenshot (and luckily, I often have to send screenshots to people, so at least I know how.)
Perhaps I should explain: what I've used in the past is an old - and I mean OLD - version of Mixmeister. It's actually aimed ad DJs, but a friend (who gave it to me for free, since the version I have isn't even available anymore) pointed out that I could just use it to play my tracks and ignore all the "bells and whistles".
It works...ok. Kind of glitchy at times. BUT, it was very easy for me to understand and use, right from the beginning. Here's a screenshot I found via Google images. I had mine set a bit differently; I hid the Master Output (which is at the very bottom in the screenshot), and mine shows only one track status at the bottom, not four, which allowed me to make both of the windows above that larger. The left window shows my entire library of tracks, the right window is the playlist.
When I tried MusicBee, I liked it much better, one of the main reasons being the ability to increase the font size. As I've said, I'm 66-years-old. I've had eye surgery on both eyes and, while I can see fine in normal circumstances, trying to read a font as small as Mixmeister's has been an issue.
Therefore, when I downloaded and installed MusicBee I was trying to more or less duplicate the way Mixmeister is set up but with a larger font size.
I was also trying to add my tracks to MusicBee's "library" (or whatever the correct term is), and then create a Playlist.
That's where things more or less fell apart. I couldn't seem to remove all of the album info, album art, etc. And, based on psychoadept explaining "...there's a difference between the Playlist and the Playing Tracks list" I now realize that I have no idea of what the heck I'm doing!
If there's a manual, or tutorial(s), etc. that could "take me by the hand" and walk me through the process of doing what I'm trying to do, I'd appreciate it more than I can express.
Again, thank you, all.
