In the albums view, when grouping, e.g., by year, the year is displayed, and below there is a splitter line.
But when grouping by Artist or Album Artist, instead of below the name, the line appears below the albums, and next to the name there is a play icon (that doesn't play, just expands the first album).
I've tested with a virtual tag asigned to Artist and Album Artist tags, and this way it works as it is supposed (the name, and the splitter line below, without the play icon).
