Madonna's Veni Vidi Vici is all about referencing her past work and it's impact on both herself and pop culture.

I took a holiday

referencing her song Holiday

I expressed myself, came like a virgin down the aisle

referencing both Express Yourself and Like a Virgin

And when it came to sex I walked the borderline

Referencing her Sex book and Erotica album and how boundary pushing they were in regards to representing female sexuality in media.

And when I struck a pose all the gay boys lost their mind

Referencing Vogue and her status as a gay icon

She also references Justify My Love, Like A Prayer, Ray of Light, Music, Bedtime Stories, and I'm sure there's a number of other references in there I've missed.
