To a Hammer is a sweet little pop/folk love song by the adorable Erin McKeown. If you like this song you might want to go to her page on Epitonic where she has two other songs available for free download. Erin McKeown is one of the artistes on Ani DiFranco's Righteous Babe Records. I'm a big fan of Ani and many of the artists she publishes. If you like this socially-conscience singer-song writer type of music check out the Righteous Babe Record page on Epitonic.
And of course the BPM, To a Hammer has a perfect 90BPM, which will help you hit that 180SPM cadence when your running.
