I don't give HP a credit even though my computer is a critical part of my writing & production process.

I don't give Microsoft a credit even though I use Word for my lyrics.

I don't give Reaper a credit even though it is my DAW.

And I don't give PG a credit even though I used RealTracks.

And no one cares!

It was always a fairly meaningless gesture but even more so today when no one will ever read your credits anyway.
