I think this song is about growing up in a family/town/community that just settles for the norm ("Nobody ever had a dream round here"), but he has bigger plans for his life ("I've got this energy beneath my feet like something underground's gonna come up and carry me"). Like chasing his musical career (as this was first album after their breakthrough Hot Fuss) but people don't believe he can do it (" People criticize him for wanting to break out, for wanting to see the world. He's sick of everyone holding him back. He knows he can make it in his life as long as he comes back home, because his 'sentimental heart' is tied to his home.") and in the end he chooses to follow the temptation & his heart ("You know I see London, I see Sam's Town
holds my hand and let's my hair down")
