What song should I learn on piano next?

Alright so I started playing piano when I was 7 and took lessons until
I was about 10 or 11. (now 15) This year I started practicing again
and I've learned pretty easy songs and some classics and also some pop
songs. I want to learn a bunch of songs this summer. Classical and
some fun stuff..Any suggestions?

Here's a taste of what I know you so you know what level I'm at
-Moonlight Sonata -Beethoven
-Fur Elise- Beethoven
-The Swan- Saint Saens
-The Rainbow Connection
-A bunch of songs from disney movies like can you feel the love
tonight, tomorrow, beauty and the beast etc.
-The Prayer- Andrea Boccelli
-Apologize
-The Entertainer
