Not that high. Spotify uses some pretty tight compression (not good, just tight); most users get 96-128kbit/s AAC, premium can go a bit higher if opted in. That works out to about 16KB/s or 58MB/hour, assuming nothing’s cached.
Bandwidth pricing very much goes down with scale, not up. But even the non-committed AWS pricing at Spotify’s scale is 2 to 3 cents/GB. You end up paying way less than that with any kind of commitment and AWS isn’t the cheapest around to begin with.
Have you ever looked into the operating costs of having a server with music on it which over 400M monthly active users use?
I actually work in cloud engineering and regularly price this kind of thing up.
Their costs are salaries not aws bills.
