I have a similar issue with a song ive had for about three years. I have a great chord sequence for Verse - Mid8 - with a nice hook, but I cant for the life of me, develop a lyric for it??
My initial hook line “I just love the things you do", I feel is too vague, the word "things" for a start.
But, I feel trapped by the initial idea and its form, and anything else I try to re-write the melody to, just isn’t right haha drives me mad.
