Perhaps they'll listen now (???_

Hello, I love the song "Vincent" by Don McLean/ 1972. In this verse of the song, I wonder if it is:

Perhaps still (not) listen now (instead of Perhaps they'll listen now)

Please help! Thank you!

And now I understand what you tried to say to meHow you suffered for your sanity
How you tried to set them free.
They would not listen
They did not know howPerhaps they'll listen now (???)
