Is there anyway to merge mp3 file?

[pouralise]

I want to download some mp3 file and merge them into one, is there any way that I can achieve it?
I also want to ask if I can add meta data such as information about artist, genre, album to the audio file?
And is there any chance that I can use some command line tool such as yt-dlp and ffmpeg on Logic Machine?
Thank you.

This is not a task for LM. Consider using RPi or similar hardware for this.
