Lyric discussion by gement 

I've tried listening for the God and heroin interpretations, and the lyrics don't support either for me. (If they're personally meaningful to you, that's still great. I find tangential meanings in all kinds of songs.)

The most common word in the song is "your," which could be targeted at anything. The second most common is "favorite." Drugs don't play favorites. Some people feel that they are more favored or chosen in God's eyes, and those people are often scary. That option's still on the table.

"Here" is also prominent, and with the title it's a distinct place, from which the singer can be removed or in which he can be kept. There's no agency here. He might as well have said cage instead of room. Gods don't generally keep people in rooms. They don't generally have fleshy, breathing "feeling with your skin" relationships with people. I've been kept in my room by mental illness, and some people have very physical metaphors for that sort of thing, but even my depression doesn't control whether it's night or day.

What controls night and day is a torturer. Consensual or creepy (or both, if you're into that), these lyrics are describing the kind of very physical, very intimate control a person can exert over a prisoner. From Dominance/submission to Stockholm Syndrome, this is the obsessive monologue of someone who has only one human contact to focus on and no control. "Favorite" captures the way a captor's focused attention is interpreted as love. In a D/s game, that interpretation's probably right, but humans seem wired to believe it no matter the circumstances.

This is actually the kinkiest mainstream song I've ever heard. It's an intimate description of an erotic act (or fantasy or abuse) that's rarely talked about.
