Musical questions

As the title implies, this is a question about the music, because not everything is covered in the credits;

1)Lola's Ringtone: Just who is the girl singing "Me, Myself and I?" I did some Google searches (and others), but so far all have lead me down the wrong road.

2)Psychic Rockets: Just what kind of band are they supposed to be? They don't sound like emo or punk, certainly not any form of metal, and something about them doesn't convince me they're supposed to be a boyband.


Any ideas?
