How can you see song file sizes on an iPhone?I have an extensive collection of CDs that are not on Apple Music. Ripped some to ALAC on my Mac and added to my Apple Music Library. The files appeared on my iPhone and their sizes match those of the ALAC files on the Mac. Unfortunately, no lossless icon, but since the file sizes match, I believe it's safe to assume that local ALAC files are no longer converted to AAC when added to Apple Music Library. This is a feature I wanted for a really long time.
It seems that Match works with ALAC files. When I added ALAC files of songs that are in Apple Music catalog, they were matched and the file sizes correspond to those in Apple Music instead of my locally ripped files. However, the metadata matches that of the local files. Also, the lossless icon has been added to the album.
