I like to sort my music by (custom) genre, but I greatly prefer music apps that organize music by Genre > Artist > Album instead of Genre > Album.   It makes album selection easier to browse if each album is nested under its own artist, but I don't want Film Soundtracks on the same screen as Jars of Clay or Led Zeppelin; and if I want to browse just Christian music, Skillet and Plumb would only list one artist entry each, on a page of 50 items, instead of 5 or 6 albums each on a page
