Summer time songs?

Ok.... so it's more like spring time, but all the same! Me and my friends have been sitting outside our dorm, soaking up the sun, and listening to some jams, but we wanted new music to listen to! We are all in charge of making a playlist today. We like songs like 'Pocketfull of sunshine' by Natasha bedingfield. The songs don't have to do with summer, just fun songs that make you happy!
