Right, and their business case probably evaporated when Apple introduced lossless for no additional charge! The bit rate for a "CD-quality" stream is around 4x that of the normal Spotify stream, so they will likely incur significant costs to upgrade their server and internet infrastructure. They question they face is whether such an investment would pay off in terms of boosting subscriptions (unlikely) or retaining customers (possible). My guess is that it is looking like a no-go for now; only if they start to hemorrhage customers will they act.
