I like your poetry but I'm still confused. Is this "Chill" or not?

Where would you post Ben Neill's Dream Phase?

I have 3 suggestions.

1) This would require some effort: Create a central reference wiki page for your genre codes. Get fancy and use tables if you must (commenting). List all the music subs with their topical focus and/or genre(s). Link it on all your subs.

2) Medium effort: Currently your #3. is confusing drifting from one sub to the other and back again. I recommend you break it up into distinct definitions: A) "This sub is for..." including your poetry and common genres (links to Wikipedia would help tremendously), B) "This sub is not for..." including other related subs and genres, C) "Overlaps may include...", D) "...but may not include...", E) "Not to be confused with...". After clearly explaining A and B, you might not wish to define the other subs in C and D, but I would include more info than less - plus I recommend copypasting your definitions (and genres) across all your music subs to be universally consistent, even if not completely understood.

3) Simplest: You could leave your sidebox as is, followed by a --- separation, then use common genres and laymans terms to describe the sub.

I have a lot of music I'd like to recommend. I would even create music genre subs with "normal" names. But I don't want to be redundant and create competing subs for the same general vibe and I'd rather support what exists. The problem is I'm just not even sure what already exists or am confused by them.
