Applications Built On Our Platform
Over 350 applications have been built using The Echo Nest's music data APIs and developer toolkits. Here are some of our favorites.
What's in a key? Are you a major or a minor person? Are there keys that define your music taste or are there no patterns at all? I've always been mildly curious about questions like this, so when I discovered the Echo Nest had a new search API that could retrieve key and mode information from song titles alone, I jumped at the chance. The project also fit my two other music hack day criteria, namely being utterly useless and involving colourful pie charts. Features: Takes your Last.fm username as input and retrieves your "favourite songs" by combining your top 50 tracks by playcount (overall) your top 50 tracks by playcount (last 6 months) your last 50 loved tracks and then removing duplicates. Queries the Echo Nest for key and mode information for each track, provides ive-updating pie chart of key distribution, gives a breakdown of major vs minor keys. The background gets lighter when it detects a major key, darkens for minor keys. Sample songs in the given key (plus mp3 samples, click to start/stop playback) when hovering over pie chart sections. Caches song/key data to speed up subsequent lookups.
