You can mention me as one of the creators of the soundtrack of your project like:
-Example 1: Soundtrack by: Eclizpdiac, [artist 2], [artist 3], and so on.
or
-Example 2: Song ["Brave reaction" and "Eleuxelier"] by Eclipzodiac
You can put it at the credits of your project or in your project description. Do it as you like. The thing is that when people listen to the songs they can check the name of the artist if they like.
