@beriangel @KUROKURO based off the image, the arist is someone by the name Jamie Brown. And the song name is Sunset of Ipanema. The author of this series most likely made up the name and artist of the song (just based off searching the lyrics and artist and looking through many jamie brown artists albums to no answer.)
Heya heya, I make lists of manga for anyone to read!! (im still working on many!!)
