Really great job, thanks for sharing. How did you create the MP3 files or do you have them from a free database?

I was able to solve that problem.
MPD port was double busy. Apparently 2 instances of Mopidy were running.

Now the module MMM-MPD runs under a few specials:

During the installation the folder name has to be changed according to the config file.
The config file value maxRows must not be 0!
The display will only update after a song change!

It was hard to find this specifics, but I thank everyone for the help!

@sdetweil thanks for helping me.

I have the code (pastebin) who put the data, i‘m looking for, in a HTML Output. If i open the html file like this

file:///home/pi/MagicMirror/modules/test/mopidy.html

everything is okay.

But if open this HTML File with the Mirrorpath like this:

localhost:8080/modules/test/mopidy.html

It shows me nothing. And i wonder why.

No, i want to show the current playing Track from mopidy.

Either by MMM-MPD (i didn‘t get to work)
Or by the Code i found on the web ( i didn‘t get to work)

i have the following problem, i want to show the current playing song from mopidy, so i install the MMM-MPD module, but it shows me only a play button, nothing else. So i try another way and i found this code in the web:

https://pastebin.com/7e40507n

Now my problem is, when i open the file:

file:///home/pi/MagicMirror/modules/test/mopidy.html

it shows exactly that output i want to see.
But if i open:

localhost:8080/modules/test/mopidy.html

or try to put the code in the index.html it shows me nothing. Can anyone help me to find out, what is blocking the code? Thanks!
