Does song discovery interest you? If so, you should be happy to learn that WhoSampled has just hit Google Play, allowing users to go through decades of music DNA. With the service, users can go through their favorite tracks to see if other artists have sampled the music or have even made remixes of the songs, all listenable right through the app and a YouTube API.
For example, if I have a bunch of Daft Punk in my library, the application will recognize the music, then show me the songs from history which Daft Punk sampled. The main goal is help users find more music that they will enjoy and share with others.
The app features charts you can search through for various categories such as samples, remixes, and covers. With such a deep library, you can get lost in WhoSampled.
The app is completely free to download, so if you love music, go check it out.
