The Boyz Members

Hi everyone! I currently listen to a bunch of the Boyz songs, they really make amazing music. Unfortunately, I’m having a hard time learning the members and it’s something I would really like to do. Therefore, I just wanted to ask if anyone had any suggestions on how to remember who is who. I have always felt way more connected to groups when I learn more about the members. At the moment, I do know 5 of the members. Just wanted to ask for some help. Thank you!
