Spotify just raised a ton of money to take on Apple’s new music service

On Monday, at its annual Worldwide Developers Conference in San Francisco, Calif., Apple announced the coming launch of Apple Music, its own digital music streaming service. On Tuesday, Spotify closed a massive new funding round worth $526 million.

The investors include Goldman Sachs (GS), GSV Capital, Asset Management Partners, D.E. Shaw, and a number of British and Canadian groups. Another one of the investors is Swedish telecom company TeliaSonera, which put in $115 million and, according to Bloomberg, has obtained a 1.4% stake in Spotify.

The new round amounts to a Series G for the Stockholm-based startup (it has raised $1.1 billion to date), which is helmed by founder Daniel Ek. The round also gives Spotify, already a tech “unicorn,” a new valuation of $8.53 billion, up from $8 billion. For those keeping score, that’s more than double Pandora’s (P) current market cap, and it’s nearly triple what Apple paid for Beats By Dre.

This funding round had been in the works for months, long before Apple’s announcement; the Wall Street Journal first reported the round in April, although it predicted the round would be just $400 million. Still, the round’s official closing on Tuesday gives Spotify some news of its own, after Apple achieved big hype from its big reveal on Monday. (As Coins2Day‘s Philip Elmer DeWitt pointed out, the Apple Music announcement “occupied the coveted ‘one more thing’ spot” at the end of the event.)

Digital music companies — from Spotify to Pandora to Rdio to Jay Z’s Tidal — are facing increasingly hot competition from rival players, and from bigger, broader tech giants such as Sony (SNE) and Google (GOOG).

In the wake of Apple’s announcement about Apple Music, there has been an attitude among many that the space will become a two-horse race between Spotify and Apple. Spotify’s big new round bolsters that prediction and makes a big statement.
