YouTube Music login issue with two accounts on one

Same issue here.

I got the same issue, even tried to log in directly into the brand account which doesn’t seem possible. Please resolve this issue, almost every other platform that has a YouTube login has an option to choose the account after logging into the google account.
Thank you  

I've found the below solution as mentioned in an older Reddit topic.

"My main account on YouTube is not the one i usually use. But i found one way to do it,and it's pretty simple. On the account the app logged on to, add all the playlists you want from your main account. The trick is ,.on the search tab write your main account name ,and the profile you're using will find all the playlists attached to your profile. And if you want to be more specific, write your account name and the playlist name. It's pretty simple, until they work around that issue, I think this is the only way. The search tab is in the upper right corner of your YouTube music channel (Magnifying glass symbol)"

^{I'm not a YT Music user myself so can't confirm. I only use the free Playrun app to listen to various free dance music podcasts.}
