Running on Empty

[Verse] Clock's ticking loud tonight Can you hear it Every second feels like a fight Can you feel it Another step into the light But is it real [Prechorus] We're chasing shadows in the sun Running faster [Chorus] Running on empty Are we really free Running on empty Or just a machine [Verse 2] Skyscrapers pierce the sky Steel and glass Reaching for a reason why Going too fast Is there something we deny Something that lasts [Prechorus] We're chasing shadows in the sun Running faster [Chorus] Running on empty Are we really free Running on empty Or just a machine
