I habe an issue with the app on my Xiaomi Pad 7 Pro. The volume of the songs always change after playing them again. Does someone else have this issue? What can I do? 

Thank you very much for your help

The volume for each audio track is saved independently. There isn't a way to change the default audio volume at the moment, although users have asked for that, and it's on my list of things to do. So for now, if you don't like the default volume, you have to adjust it for each audio track.

I use "mp3gain" for output leveling (batch process) on PC.

That means, all mp3 for usage within MS I check before (or let do the work mp3gain).
You can filter all mp3 by a file explorer and check/change it at once.

IMHO that´s the easiest and fastest way.

Getting an even mix balance between songs can be tricky if you don't know what you're doing.

A quick and dirty way would be to put all the songs you need in your set into Audacity (free) as separate tracks and then normalise the gain on each one so that it's just below 0dB e.g. -3dB (to prevent peaking). Then mute all the tracks except one and export that one track. Mute that and unmute the next one and export that and so on. You'll find that they'll all have roughly the same output volume on your tablet.

NO!

That is not the solution to the problem.  There is a big difference between simply normalising a batch of songs to the same peak level and making their relevant loudness the same.  If you only normalise all the tracks to the same level, there will still be a difference in perceived loudness and the initial volume problem will remain.

The way to do this is to use a program such as MP3Gain, as noted in an earlier answer.  This will set the perceived volume of each track relative to the track you pick as your 'standard.  For .wav files, there is a program called Volume Balancer which achieves the same end.

Actually, having re-read the OP, I'm not sure if this is his problem.  He seems to be saying the volume is different on a second play of the same track, which seems to be very strange behaviour to me.
