It seems that F5+ and Garmin Express incorrectly handling "Artist / Album Artist" mp3 tags. I have few albums like a "100 best running songs" that is obviously a single album but every track has different artist. So, in the watch all tracks become split over artists and terrible showing as 100 albums! In contrary, in GE the same issue exist with "Album Artist" tag. So, to make such albums properly work in both GE and F5+ I have to make all three tags "Album/Album Artist/Artist"equal.
I just curious, if anybody don't care or maybe there is workaround exists? So odd that such basic bug that is more typical for the very beginner programmers seems exist for years in Garmin.
