I from Gen Z . Can you you reproduce this list with songs I might actually know?
Got it, my mistake. As a member of Gen Z, you're probably looking for some more contemporary tunings and song examples. Here's an updated list of common guitar tunings with some newer songs as references:

Standard Tuning (EADGBE):
Example song: Shape of You by Ed Sheeran

Drop D Tuning (DADGBE):
Example song:  Basket Case by Green Day

Open D Tuning (DADF#AD):
Example song: I Will Wait by Mumford & Sons

D modal Tuning (DADGAD):
Example song: Wonderwall by Oasis

These tunings are commonly used in modern pop, rock, and folk music. The fingerings to play G, C, and D major chords are the same as in the original response. Let me know if you would like help finding tabs or tutorials for how to play any of these songs. I can also provide additional resources on using these tunings and playing contemporary guitar styles if that would be helpful.
