Aeropostale Song: "I'm Always Sure Of Where You Are"

I was in Aeropostale the other night and I heard this really great song but I only caught a small phrase. "I'm Always Sure Of Where You Are." Something Something Something Yadda Yadda Yadda. So if you could help me I'd really be thankful. I've already tried searching google and I haven't found it yet. It's sung by a female artist and it sounds alternative rockish. It's a great song and if you could help me find it that would be great. It's NOT by Bbmak or the Goo Goo Dolls. Please post!!

I found a song by Apples in Stereo called "Sunndal Songs"....its a girl and it sounds alternative...hope this helps! =) This is a link of it on Youtube:
