The Hills : Jason Returns

What is the song being played while Lauren and Audrina are talking about going out without any boys? The lyrics go something like this:

"Summertime days, sun is hot here in L.A., got to stay up or you get left behind..."

Did you find out what the song was? I did a lyrics search & still can't find ANYTHING!
