Tom Dunne: My bloody Valentines - six songs that show the dark side of love 

Forget the flowers and compliments - some of the best songs about love have a bit of badness in them 

Leonard Cohen, Amy Winehouse and Ryan Adams have doled out some of Tom Dunne's Bloody Valentines.

The devil has the best tunes. Best of luck to The Osmonds et al, but it’s Robert Johnson – the man who sold his soul to the devil – and all those influenced by him since (Dylan, The Stones, Led Zeppelin) who make the pulse race.

It is the same in Love. As we faced into another Valentine’s Day earlier, and radio assaulted us with either maudlin assertions of undying love or sickly-sweet contemplations of puppy love, be in no doubt: it’s the people with a bit of the devil about them who write the best love songs.
