Hello, everyone!
I decided to join the NGAP20AP and I found out that vocalists(rappers included), voice actors and podcasters can join too. There is a shortage of them in the collab, so if there is anyone that is a vocalist, voice actor or podcaster and is interested to join, you can do so here: https://www.newgrounds.com/bbs/topic/1519057. There's also a Discord server, which I recommend to join. There are many musicians in the collab that are really up to collaborate with you, myself included, so give it a shot!
