Positive Life Radio - http://www.plr.org/
Do listen to this, it's real good stuff, uplifting alternative Christian music to widen your exposure to Christian Music, and best of all, it's free.

Also, Mark Conner's Blog - markconner.typepad.com
I have been reading this for a year, and it has amazing illustrations and he talks about things that are really relevant to the real world, so it's cool.

Podcasts & Sermons - http://www.generationchurch.org/podcasts/
Generation Church, a US based church has dynamic youth speakers and their sermons are strongly rooted in the word. Pretty interesting sermon titles too: Eg. Get Up and Glow, Paddle Battle, Running on Fumes (getting God's attention) and Faith That Fights. Good stuff. Must listen to build yourself up :)

Love,
