Popular music app Shazam, which allows users to identify music through their smartphone’s built-in microphone, has announced a partnership with online dance retailer Beatport.

The deal immediately expands Shazam’s catalogue by around 1.5 million tracks to 25 million, the London-headquartered service claiming that its technology will still be able to identify dance tracks that have been sped up or slowed down, layered with other sound effects (including bullhorns) or partially obscured by crowd noise.  Shazam reached over 275 million users in 2012.

Will Mills, Director of Music & Content at Shazam, commented that over 30 of the top 100 “most tagged” tracks of last year were dance ones.  “From Ibiza to LA to Tokyo and beyond, fans of electronic dance music... will now be able to experience more of the dance tracks they love every time they use Shazam when they go out” he added.

Matthew Adell, Beatport CEO, said:  “Adding the Beatport catalogue to Shazam’s database is a great way for fans of dance music to discover songs that are being played by DJs all over the world.  Our partnership also gives DJs and producers exposure to an enormous audience of potential new fans.”

The Shazam app, compatible with Apple, Android, BlackBerry and Windows smartphones, can send users back to Beatport to buy once they have tagged the music they like.  Users can already re-direct to iTunes, You Tube (to watch related videos) and social media hubs like Facebook (to send notes to friends and contacts).
