Characteristics of the song?
This is more about Bulbapedia as a whole, but should it include characteristics of songs such as genre, key, tempo, progression, etc.? A NIWA wiki that does that is Inkipedia (Splatoon), where it has pretty thorough descriptions of the game's music tracks, and even includes genre designations like metal, electronic, vaporwave, etc. I think Bulbapedia should do the same. For example, Battle Cry -- Stand Up is a hybrid of electronic and rock, and Rival Destinies is rock.
