The is tool aggregates the top tracks from the most popular public playlists on Spotify that match your search criteria. Looking for the best workout tracks? Enter the term workout and find the tracks that have appeared most frequently in workout playlists.

I've always missed iTunes' genres and other forms of catergories. Spotify doesn't have these features...until now! It's now easy to make playlists by genre, mood, and even decade, rather than having to trawl through your music song-by-song!
