听过很多情歌却还是单身
[tīng guò hĕn duō qíng gē què hái shì dān shēn]
'Heard many love songs but remained single' implies the speaker has experienced or understood the romantic expressions contained in music but still hasn't found a partner, leading a single life. There's an undertone of longing for love or finding companionship, tinged with some humor and irony.
