>There have been tests showing we cannot hear the difference between minimally lossy audio (e.g. mp3 320kbps) and lossless. But Balvin can. And it sounds "bigger and stronger".
Yes, but lossless audio is still useful for transcoding. If you want to play music on your phone, and you have plenty of fixed hard drive space on your desktop (which is very cheap), it's rational to compress with an advanced codec to ~90 kbps since your headphones probably aren't good enough to pass anything more hi-fi and you want space for pictures and videos. However, if your downloads come lossy compressed, you'll introduce transcoding artifacts; you can get around this by transcoding at a significantly higher bitrate, but now the compressed file is wasting space!
