How to create a program to collect the names of music files into text?

Question

C++ / C#

I'm switching to a music service from music piracy. I have already accumulated music (About 1.5k tracks). And I really don’t want to transfer everything with pens, especially since I’m studying to be a programmer.
The question is: what do you need to know/learn to create a program that just needs mp3s, and the program read all the track names and formatted them in a suitable format for me. Later, for the beauty of the picture, I would like it to add to the playlist itself, which I will indicate the tracks.
Languages ​​I can use: C++/C#. The service to which I want to transfer all this is Spotify, or to the extreme YT Music.
