Consider a historical album like Neil Young's 'Decade' for which the 'Album Artist' should be Neil Young, but for each track the 'Artist' should be more appropriately (e.g.) 'Buffalo Springfield'. I hate it when I copy the tracks to a device for which the player pays no attention to the tag 'Album Artist' and makes it difficult to play the album in its entireity.
I thought... I'll copy the files, but with Windows file explorer, I'll change the properties, 'Artist' to Neil Young for all tracks, and this slight modification would be independent of MC's library. However, to my surprise Windows shows 'Album Artist' but doesn't show 'Artist'. I thought this was kinda weird, but thought this may only be trues for AAC encoded tracks (m4a), but then found for MP3's even fewer tags are shown, also excluding 'Artist'...
I also noticed that Windows shows a tag called 'Contributing Artists", which MC does not(?)
