Does anyone know any songs similar to these?

I love like songs with piano in them. I love when people can play the piano and stuff because its such a beautiful instrument to me. I love the songs Dreaming With A Broken Heart by John Mayer, Breathe Me by Sia, Waiting Outside the Lines by Greyson Chance, Boston by Augustana, Beautiful by Christina Aguelaira, What About Now by Daughtry, You Found Me by The Fray, U Smile by Justin Bieber, and Fuzzy Blue Lights by Owl City. I like all of these mostly because they have piano parts in them. If anyone knows ANY similiar songs or artists I'd be happy to hear them.
