a change of heart

Lyrics

well i guess you must have had a change of heart, you don't treat me like you used to at the start, your campaign of love was quite a work of art, but i guess you must have had a change of heart, guess i took too much for granted anyway, but it's just cause i'd believe the things you'd say, not so long ago you'd swore we'd never part, but i guess you must have had a change of heart, well good-bye to all those castles in the air, and good-bye to all the dreams we used to share, they were fragments of a dream that fell apart, now they're gone because you've had a change of heart
