Song in the radio car when they together, any help?

Hi, i saw this film recently and like a lot. I would like to know who plays a song that sound in the radio car when are together. She doesn´t like what it´s playing in the radio and change until she finds a song she likes. She sing the the words and say: " I like this guys, they are authentic" (or something like that). I´ve seen the list of songs in the film but I don´t know who plays this song . Maybe The Connellis?. Thanks if anybody can help.
