Pandora updates its iOS and Android apps with personalized station recommendations
The recommended stations will appear at the bottom of the screen whenever you create a new station. They will pop up at the bottom of the stations list, too. The recommended stations are based on the current listening preferences of each user, which are determined by all the "likes" and "dislikes" for the songs in the station list. When users engage with filtering their own music preferences, Pandora adapts to their musical tastes and optimizes the future artist station recommendations.
The update is still rolling out, so you might not get it right away.
