I have a couple of podcasts I host on my site and I've noticed a disturbing trend the last couple of months: my site's bandwidth usage has gone up by 10x, but it appears most of it was a series of Google App Server instances, not an incredible increase in listeners. Digging through the logs, I think most of them appear to identify themselves as "Spotify/1.0," which is hitting my server several times every minute and downloading different old podcast episodes.
I'm wondering if this has something to do with me recently implementing NGINX as a caching server in front of Apache, because the spike roughly coincided with that change. Is there some issue with how I'm answering Spotify's bot? Is this a known issue with their indexer I need to somehow deal with?
For example:

The actual files being requested seem to report correct modified dates, etc. Here's the output from curl -v that seems relevant if I request one of the files:
