It will definitely go once music sales drop below a certain percentage of Apple Music subs. If 95% of your music revenue comes from streaming, why have an infrastructure to support the other 5%? Personally, I still like buying music, but I can see the writing on the wall for the current system. Perhaps if Apple started selling ALAC/24-bit music it could grab the share of the market where people want quality over convenience. Bands like Muse and Radiohead have released their last few albums in higher quality, so there must be a market for it.
