Patrick Park: Your Smile's a Drug
Patrick Park is a singer-songwriter who, like many, hasn't gotten a fair shake due to record label issues. His 2003 debut album "Lonliness Knows My Name" should be known by more than it is, there are many great folk-pop songs on there that college girls should be swooning over. He reminds me a bit of Rhett Miller's folkier more melancholy side.
The song's title tells us most of what we need to know. He has fallen for a girl who's smile he is addicted to. Despite knowing that pursuing a relationship with her will mean a lot of work and possible torment, he can't seem to help himself. She smiles, and he loses all sense of what's good for him.
