Review: MP3 Project in MVVM style with "clean code" principles and design pattern done right?

After reading the books "Clean Code" from Robert C. Martin and the "Head First Design Patterns" book from Elisabeth Robson I decided to make a mp3 tag application.

I tried to do it in the MVVM style and appy as much clean code principles as possible in the code. One thing i didn't figure out is to apply the single responsibility principle for the ViewModels where i wanted to separate the representation logic of the properties and the command logic.

Unfortunately, I don't have anyone who would review my code and give me tips to get better at coding :(

It would be great if you could give me feedback about the way I programmed it and I will be thankful for every tip you could give me.

I don't know if I'm allowed to post such a question in the stackoverflow forum. Maybe you know a website where I could ask such a question?

Here's the GitHub link to my project: https://github.com/multi-kulti66/MP3_Tag
