The uploaded format from iTunes Match is put in the personal Apple Music iCloud library. It will not be altered. All other matches to music will be in the low 256kpbs mode. Can I upload my own songs in m4a apple lossless format and listen on all devices in the same apple lossless format in iCloud library? Now I connect every device separately to store the Apple Lossless m4a music files.
Would for me make a big difference, not to have to listen to low quality sound.
