Meaning of "Black and Blue" by Snow Patrol

The lyrics of "Black and Blue" by Snow Patrol explore the complex emotions and dynamics of a relationship that balances on the edge of both passion and danger. Describing the partner with "blood red lips like soft intentions" and how they "kiss my eyes - they're black and blue" paints a picture of a love that inflicts both pleasure and pain. The singer acknowledges that they shouldn't be in this situation, that it might not end well, yet they feel helpless against their feelings for this person. The repeated mantra of "she rescues me" hints at a sense of dependency on the partner for emotional fulfillment, despite the toxicity of the relationship. The push and pull of desire and warning signs within the lyrics reflect the tumultuous nature of love that can sometimes be addictive but ultimately destructive.
