Q What's all the excitement about lossless music?

A The contemporary excitement is down to Spotify’s long-overdue concession to providing its customers with high resolution audio.

In this case, it’s better-than-CD 24-bit/44.1kHz FLAC across almost its entire library. Very nice, though Guru does suspect that more artist-friendly rivals such as Qobuz might start to pick up speed as Spotify’s reputation takes a long-overdue dip in the mud. GaGu does suppose that your question might have been more about lossless music in general, rather than why it’s in the news, so let’s tackle that. You probably already know that many popular formats are compressed to save space and bandwidth. A CD holds just over 700MB of data; turning that into MP3 files isn’t simply a case of applying a magic algorithm. Bits get sliced out. Details are smoothed away. That's loss.
