Some lyrics are as inspirational as the musings of the Greek Gods. Other lyrics make you want to kick the hair out of the head of the person that wrote them
Either way once heard they are in your head and you carry them with you pretty much forever.
I will kick it off
Best Line - “Gravity keeps my head down or is it maybe shame at being so young and being so vain” - Manic Street Preachers - If You Tolerate This.
Worst Line - “If you judge a book by its cover then you judge the look by the lover.” - ABC The Look Of Love. WTF does that mean? its bugged me for decades.
Try to keep it to a single line that resonates or annoys the crap out of you.
