Song must include a notes.chart file and song.ini and song.ogg files.

I download songs pack from here:

https://customsongscentral.com/4th-quarter-2024/

the final download url is:
https://customsongscentral.b-cdn.net/CSC%20Quarterly%20Pack%20-%204th%20Quarter%202024%20(Feat%202).7z?ref=customsongscentral.com

Most of the songs have notes.chart file and song.ini and song.ogg files, I can play them successfully.
