I'm cleaning out my gmail folders this weekend, and went deep into the archive to 2011, when I got my invite to Google Music.
It's funny, because I just (November) moved all of my music out of cloud and back to local-only. Amazon was the last straw, when I tried to play purchased music, and was forced to listen to it on shuffle with other songs not of my choosing.
Anyway... there was a time when Google (ahem, Youtube) Music was set to be a game-changer. Imagine if enshittification wasn't a thing.
And as a bonus you snagged firstnamelastname without realising.
This alone makes Gmail a better service than most providers. All of the similar but different address confusions avoided.
It really should be standard practice.
Oh I know.
There's someone with a variation of my first name (think "Steven" versus "Steve") who absolutely cannot get their shit sorted and gives out my address as theirs all over the place using "longerFirstNameLastname" but fucks it up and uses my address instead. I tried emailing them directly once letting them know, got accused of "hacking their google" and now I just delete some important looking emails like travel reservations and digital gift card redemption things for Xbox.
