FLAC is useful for listening to high quality music which hasn't been filtered and compressed. It sounds significantly better than lossy audio. Iscit so hard to comprehend that as more bandwidth comes online all the time, people won't want to compromise on sound quality the way they were forced to in the past?
This answer is just being contrary to be contrary. 'Most people' can't distinguish 1080p from 4k from 6 ft away, yet people still stream 4k content, which 'gobbles bandwidth' too.
