Nice guide ouo I always like to use music with no lyrics, or lyrics that are very flexible, when I make a character. I usually pay attention to how the music moves and feels instead of the lyrics. For instance:

Like how I think of a eerie, dark forest, with this, a place where those who were different go, a place where they learned to accept the dark and dangerous life style, and have been mutilated by the forest so much that they are more monster than animal.
Well, that was a bit off topic. For a character, I imagine that song as someone wise, who has lost practically everything they ever knew due to their kind refusing to change whenever it was needed. They're alone. The fact that he/she abandoned their kind because they were too stupid to realize that they were about to be demolished haunts them.
hnn. But yeah. Trying music like that can seriously give good inspiration. A character that's moulded from the feel of a song has the ability to be very complex, unique, and memorable, at least for me.
