1. The Spotify saga continues. Days after artist Neil Young pulled his music from Spotify in protest of vaccine misinformation on Joe Rogan's podcast, Spotify has responded. The platform will add content advisories to podcast episodes that discuss COVID-19. It is also making its COVID-19 content policy and platform rules publicly available on its site. Here's what's happened so far:

• Other artists have followed suit: Joni Mitchell announced she would also pull her music from Spotify, while author Brené Brown said she won't release any new podcast episodes "until further notice."
• Meanwhile, rivals have wasted no time cashing in on the drama. Amazon, Apple Music, and SiriusXM have all offered special deals to new listeners — like Amazon's free four-month subscription trial.
• Apple Music has also proclaimed itself "the home of Neil Young," and added a "We Love Neil" section to its homepage. SiriusXM announced that it'd air its "Neil Young Radio" program over the next week.
• By Friday, Spotify had lost billions in market value, with shares down by 12%.

The Verge has the rundown on Spotify's response.
