Songs Help!

Hey so I'm trying to find these songs but I don't know who sings them.

The first song I'm looking for was playing during Jason and Vanessa's sex scene in Season 1, the episode was 'Model Behavior' I believe.

The lyrics go 'Boy you make me feel alive, Yes you make me feel alive, you look so good, love to make love tonight'.

The second song I'm looking for was playing in the last episode of Season 1 at the end when Jason and Lacy had sex in the back of the truck. I believe the episode was 'Rags to Riches' and the

lyrics go 'Feeling so restless, Feeling my world changing, But something tells me don't be afraid...I want to fall in love (with you)

If anyone knows the name of those songs and who sings them I'd really appreciate it :) Thanks!
