[DJ-AS]

I got eye strain looking at your cue sheets image but I think the issue is related to having multiple cue sheets with the same TITLE element e.g. "DJ Mengano - DJ Klub (CDC, Mixed-2000)". Kodi allows for an album to be split across more than one music file, taking the album from TITLE and PERFORMER pair, but nothing from the file name. The FILE element just identifies where the music is located. Hence with your cuesheets it results in albums with multiple track 1 etc. (with different genres).

For example album: "DJ Mengano - DJ Klub (CDC, Mixed-2000)" will have songs <name, track number, genre>
"Reach (unknow version)",  01, "Tribal,  House"
"Samb Adagio", 01, "Trance, Progressive"
"Prosac (Tony II mix)", 01, "Techno, Hard techno"
...
"Feel This",  02, "Tribal,  House"
"The Taste of Summer", 02, "Trance, Progressive"
"Taub (Mario Pico mix)", 02, "Techno, Hard techno"
...

To get the result you want you will need to alter the cue sheets to have "Tribal", "Trance" etc. in the TITLE element.

Or if cuesheet changes unacceptable, you could explore what selecting via genre does. There is no sorting by genre, but if you navigate from the Genres node, say selecting "Trance, Progressive", then to the album "DJ Mengano - DJ Klub (CDC, Mixed-2000)", it will filter only the songs with that genre.

You're the best Daveblake, you have right, I change the album name in the cue sheet and now I have 4 "Albums" with the correct songs each one.
Is there any way to make that 4 "Albums" appears in one node? Like this:

Folder: DJ Mengano - DJ Klub (CDC, Mixed-2000)
Subfolder: Tribal - House
Subfolder: Trance
Subfolder: Techno
Subfolder: Electro
