Replace Last.fm playlist tracks automatically on a Reddit playlist
Using a music recommender system called Audioscrobbler, Last.fm builds a detailed profile of each user's musical taste by recording details of the tracks the user listens to.
Reddit is a news, content rating, and forum social network. Registered users submit content to the site, such as links, text posts, images, and videos, which other members then vote up or down.
