1audio - not sure I follow your concerns. In what way do you mean they are stored by artist rather than album? Obviously, there is the file/folder structure, and that isn't effected by LMCE. But in terms of the sorts, this is based purely on the attributes of each track as I understand it.... the media grids are (supposed to be) constructed by grouping together tracks, first by your sort criteria, then by secondary attributes... in fact this is one of the things that I have logged as an issue. After sorting by album, it is breaking up "compilation" albums into multiple entries because all the tracks have different performers (I believe) unlike normal albums. But this is clearly not by design, and they have already tried to fix this. But it seemingly didn't work. Either way, it isn't a design element.
Moreover, there is an issue here of nomenclature. The GUI menu says "Sort" but in fact it is a grouping. The "sort" is always the same, alphabetical. Then under those grouping, there IS a sort - previously it was also alphabetical. I logged a mantis to get this corrected because you don't want your tracks played alphabetically, you want them played in track order (typically) but this is what it was doing. I have checked with Beta 4 - it does still display them alphabetically, but when you hit Play All it now correctly adds them to the play list sorted by the track attribute.
There are distinct sorts, filters and groupings, but the naming seems to be inappropriate which causes confusion.... I'll shut up now, because I haven't actually got a point
