Actually, i do not dislike the fact that rock and pop are grouped under big parent genre Rock/Pop. I mean, in my previous Logitech Media Server library, i used to have 3 big libraries: Classical, Jazz and Rock/Pop. It makes sense to me.
In general, i find it difficult to say “this is rock” or “this is pop”. But i’m not a genre classification maniac…
Nevertheless, there are albums/artists that i feel like more Pop (Madonna? Early Beatles?) and album/artists that i feel more rock (Springsteen?)…
More than that, i think that in the big family of Rock/Pop, the various sub-genres are more “rock” or more “pop”…
So, in general, the roon/allmusic logic works for me. Except that in roon, under Pop/Rock, there is a Pop subgenre, but not a Rock Subgenre. This doesn’t make much sense. Actually, i have a Rock Tag in my files…, so in my library settings i said that it’s a Pop/Rock subgenre. I could define all other roon “Rock” subgenres to be… subgenres of my Rock, and it would be ok. I guess.
On the other hand, I agree that… all various subgenres (of Rock/Pop, but also of Jazz and Classical) are not very satisfying (for me… “alternative” , “indie”, “adult”… do not make much sense…) and i would like a simplified hierarchy.
So, i agree that the possibility to edit in a better and easier way the library genres hierarchy would be very very appreciated.
There’s another point, though, that i really dislike: international music. i mean, it seems that what is not English-american… is international, and i think this is quite “closed-minded”. if i look at italian music… it seems that there are “italian pop” or “italian folk”… but not “italian rock”. i don’t know, it seems that the same concept of a hierarchy cannot work to distinguish regional music.
in my opinion… regional identification should not be a genre at all. the overall genre hierarchy would be simplified (see discogs).
then, there could be an additional “regional filter” if you want to select a particular genre coming from a particular region/country. in a way, it would be as if every genre had a regional sub-genre.
there are also specific genres that are strictly regional, in the sense that they are present only in a specific country/region, and cannot be seen as regional subgenres (i don’t know, flamenco? mongolian throat singing?). i would put all these under a “world music” parent.
i think this is the logic i meet in general in music stores… and it works.
