Spotify is testing a lossless subscription tier for $15 to $20 per month

What is lossless quality anyway? Currently, if you go into Spotify’s settings and choose the highest quality, Spotify serves you 320kbps audio files. It’s very high quality, but it’s not perfect — in other words, it’s a compromise. This way, files are still quite small and load quickly. Lossless files are perfect copies of the songs on an audio CD. They are then compressed, but without any quality loss. It’s like songs are copied from a CD to your hard drive and then “zipped” to reduce the file size. An average lossless song can be five to ten times bigger than a 320kbps song. – Romain Dillet, TechCrunch
