Post author here! I wanted to make it clear that the original technique for breaking Spotify DRM is not mine - it was developed by Wang et al. in their excellent paper, Steal This Movie: Automatically Bypassing DRM Protection in Streaming Media Services. I just thought it would be a nice showcase of PANDA's capabilities. In particular, we can avoid the crazy optimizations in that paper because we can operate on a replayed execution rather than doing it live.
