As someone who had 1.6mbps dsl for a long time (up until 2018), it is plenty for streaming audio. It’ll do 480p video pretty well, and depending on bitrate can sometimes do 720p. Multiple users for video streaming is impossible, but should work ok for audio.

I have that for my deadname account, but I had to put a number in my post transition gmail account. I do have firstname@lastname as a personal domain though some sites don’t like that.
