Digital music service WhoSampled has been released on Android, six years after it was founded, according to the Guardian.

WhoSampled, which started in the UK in 2008, can now be downloaded from Google Play Store for free.

The service offers a database of songs and the samples they feature and shows listeners the songs' connection to other tracks and how they have been derived from the originals.

To show the interconnection of tunes, WhoSampled uses Vevo and YouTube videos to indicate the parts where the samples are infused. It also provides links to downloads, vinyl and CDs of the tracks and samples used.

The service, which now has 270,000 tracks and samples, released its app for iPhone users in June 2012. Unlike the Android app, it comes at a price.

Its founder, Nadav Poraz, admits that there hasn't exactly been a frenzy around the app but is aware that it has steadily been building a following.

"Up until a year or two ago, when I met people I had to explain what WhoSampled was. Now, we find so many people who are fans. It's no longer this obscure little thing that you have to explain," Poraz says.

The WhoSampled website currently receives more than one million visitors monthly, but this has been due to the start-up's own efforts and expenses. It says it is seeking to broaden its reach and attract more people outside its early audience of sampling enthusiasts.

"We have broken out of the niche of super-hardcore fans of sampling. We recently changed the title of our site, too. We used to be 'the ultimate database of sample-based music,' but it no longer mentions the word 'database,'" said Poraz.

The company's new slogan is "Exploring the DNA of music."

WhoSampled hopes to earn from their Android app via paid advertisements.
