As for artist's names:
I seem to recall PGMusic explained previously that it is because we create the songs.
The Realtracks artist has never heard our song, and likely may have played something completely different if he had.
With a little bit of audio editing knowledge we can literally slice/dice up a lot of things the artist would never have played.Good or bad.

Let alone if their part becomes the hook of the song. Then you venture into weird territories.

It really is the best for everyone, in my mind, to discourage it as far as mentioning the artists names.

I do not work here, but the benefits are still awesome
