Gone are the days of fumbling around with your iPod while on a run. Reebok has partnered with music streaming service Spotify for "FitList" a new app that generates the perfect music for your workout. "FitList," which was created by Hunted Media, lets you select a workout activity, time, intensity level and pick your favorite artists. The app will then take into account the song's beats-per-minute tempo, its "danceability" and energy level to present you the perfect workout mix.

And to match the musical sensibility of the campaign, Pittsburgh, Penn.-based Deeplocal is serving up a musically oriented shoebox as well. Read more about it in behind the work.
