@luvmytrio I moved your post over to this existing thread: Create playlists with Pandora Plus
It looks like your account is currently upgraded to Pandora Plus.
The ability to search songs and add them to customized playlists is only an option with a Pandora Premium subscription. If you'd like to upgrade or find out more information on the full benefits of a Pandora Premium subscription, you can view this page.
Alternatively, you can initiate a Pandora Premium Session which allows you to listen to content on-demand or try Pandora Premium without committing to a subscription.
For more information on how to start a free Pandora Premium Session, you can view this page.
Hope this helps!
