Mood Music started off as an ambitious idea to provide web users with content-relevant music that reflects the mood of the websites they visit. Through 36 hours of pushing our bodies and minds to the limit at HackUCI, we transformed this idea into reality. We combined text extraction, natural language processing of mood, and integration with the rdio API to create this Firefox add-on. The inspiration behind this lies in alleviating the burden of finding good music during a user’s browsing experience. We hope this extension can help users focus on browsing the web and leave their music listening up to Mood Music.
