Since it launched in 2008, music streaming service Spotify has grown in popularity across the Web. Last year, Spotify’s U.S. launch and its integration with Facebook (News - Alert) helped take it to the next level. Today, Spotify takes a step towards establishing itself in the mainstream, with the introduction of a new embeddable button for bloggers and Web editors.

USA Today reported that Spotify (News - Alert) has introduced The Play Button, which will let you embed any Spotify song, album or playlist directly through your website letting you tap 16 million tracks and allowing your readers play legal music directly on your website, similar to YouTube (News - Alert) videos.

Spotify has partnered with Tumblr, Time Out Group (NYC, Paris, London), GQ UK, Vogue, MSN, The Guardian, Virgin Media, The Independent, NME, ShareMyPlaylists.com and others, to let them offer the Play Button to their readers and listeners.

These partners are excited to be working with Spotify on this launch. Spin.com is putting Spotify Play Buttons in its reviews section.  Moviefone put together a playlist of “The Best Songs in Cinema” to showcase the Play Button capabilities. People Magazine created a playlist about “what really matters” in beauty. The playlist is called “Beauty and the Beats” and features tunes by Christina Aguilera, P!nk, Cyndi Lauper and Beyonce. Entertainment Weekly did three playlists to get thing rolling over there: EW Recommends This Week; The EW Ultimate 2012 Playlist; and EW’s 30 Greatest Artists Right now. And Arianna Huffington over at HuffPost shared her own personal playlist, called simply “Arianna’s Favorites“. It includes tracks by Willie Nelson, Alpha Blondy, The Decembrists, and Fleet Foxes.

"We deeply value music as a form of creative expression," says David Karp, Tumblr founder and CEO. "That Spotify now let’s our users share from millions of their favorite songs is revolutionary, and as huge fans of the product we are absolutely overjoyed about this partnership."

The Spotify Play Button is now integrated into the Tumblr dashboard. All you have to do is simply type in the song or album you want and Tumblr creates the widget to fit with your blog's theme.

To get the Spotify Play Button for your website, choose any song, album or playlist URI from within Spotify, and then go to its developer website to get the embed link.
