The power of friendship in gothic music

I've said it already; I'm a big goth metal/rock fan. Both gothic subgenres have many things in common, with the exception of goth rock being a lighter alternative, but there's something else I've noticed recently: friendship and romance. They seem to power the subgenres almost wholly, more than any other kind of music I've listened to. Attributes that often characterize this are "beauty and the beast" vocals, duetic & romantic vocals, and lyrics that are depedent on the strength of the friendship of the writers. In this report, I'm going to use several bands as examples of the attributes I listed.

Beauty and the Beast
The "true" definition for beauty and the beast vocals is vague with some aspects, but the aspect of a female/male duet remains true. The female vocals usually give a more submissive stance, and are usually clean, while the male vocals tend to be harsh or clean with an admissive stance. However, this is not true for all goth bands. A band that goes against this is Lacuna Coil.
B&B bands: Sirenia, Tristania, Lacuna Coil, Epica

Duetic and Romantic Vocals
This goes hand-in-hand with Beauty and the Beast, but I thought it would be good to list it since there are some gothic bands who don't seem too "beastly," or enough so much that I'd consider that they have such vocals. In this more romantic stance, the female leads tend to be classically trained. Remember, gothic music has a pretty good connection to more classical music. A good example would be the songs with male vocals from Evanescence that aren't from the albums Fallen or The Open Door. The only song that they ever made that had B&B vocals was Lies from Origin. Yes, they did have music before those albums.
D&R bands: Lacuna Coil, "pre-Fallen" Evanescence, Within Temptation (went from goth metal to goth rock with metal influences), Epica, Nemesea.

The Strength of Friendship Between Writers
The strength of the friendship that lyricists of goth bands have with each other is immense, so much so that it elevates them to whole other levels, musically. A good example of this is the incident that happened with Evanescence. To sum it down to the core: when Ben Moody and Amy Lee were really close, that's when they made the best music together. However, when they separated and made music on their own, the music just sounded so plastic; so fake.
Strength of friendship: Lacuna Coil, Evanescence, Within Temptation

I hope you enjoyed my little report!
