Those lyrics, though. They, in all their awful emotive specificity, are what secures this song its place as one of the best things recorded in the '00s. The disgust the narrator feels for his subject and for himself, his depression, his anger, his desperation, his helplessness--I hope no one reading this ever has reason to feel "Unlovable" strikes them straight to their core, but it captures the tormented state of mind of an emotionally abusive relationship better than any song I can imagine.
"Unlovable" is on Darren Hayes's excellent second album, The Tension and the Spark, which can be purchased here
