New to Classical Music, would like some piece recommendations like these

Hi! I started getting into classical music just recently, but I'm having trouble finding music similar to these, so I'd like recommendations :)

I must also say I know NOTHING about music, so I might sound kinda dumb here haha

Miserere mei, Deus - Allegri - Tenebrae conducted by Nigel Short - Just find it extremely beautiful, almost like I'm listening to angels;

mozart: Requiem in D Minor, K. 626: I. Introitus. Requiem aeternam - Also find it beautiful, uplifting in its own melancholic way.

mozart: Mass in C Minor, K. 427 "Grosse Messe" - I. Kyrie (Live) - Once again, beautiful. Don't know what else to say about this one though

thanks in advance!
