Spotify has developed a huge surface area, because they are attempting to be the one-stop shop for all things audio. The thesis is that the whole is greater than the sum of the parts, and that's what they're selling to investors. That means there are countless bets they could be making at any one time, to compete with everybody else out there.
For a company of Spotify's stature, when capital is cheap, they can raise the money to do all the things, all at once. They don't have to make prioritization choices. Usually this means many dozens of teams, which each seem pretty lean if you zoom in. Like, I'm guessing there's a team of 3ish developing the in-app lyrics experience, or something like that. The scale is in how many of these bets are going at once.
The capital markets have changed, and now Spotify (like many others) has to constrain its bets. The thesis hasn't changed, but their capacity to try to prove it out isn't as limitless as before.
