Currently a vignette is placed randomly regardless of the type of music that will play later. It is weird to play a quick vignette and the music that plays is romantic.
The Centova could put certain rules for this, or is each song folder could have a relationship with certain vignettes, example:
Folder fast songs - fast Vignettes
Folder love songs - slow or romantic vignettes.
In other words, each vignette quick to play, the Centova choose a song from the fast music folder, when a slow vignette or romantic, the Centova choose a song of slow / romantic folder.
I'm sorry if English is not correct, I used an online translator, I'm from Brazil.
