The Spotify application was launched for public access on 7 October 2008.

At the same time, Spotify AB also announced licensing deals with many major music labels. The company reported a $

The first step towards offering free accounts to the public without an invitation was taken on 10 February 2009, when Spotify opened for free registration in the UK. Due to a surge in registrations following the release of the Spotify mobile service, Spotify closed its open registrations in the UK for part of 2009, and went back to an invitation-only policy.

New users were exempt from these changes for six months.

With the Spotify radio function, users are allowed to skip as many tracks as desired, while Pandora places limits on the number of tracks that can be skipped. Additionally, Spotify does not allow users to lend “star ratings” to tracks, thus, limiting the ability to organize the radio function based on user preference.

There are currently no official details from the developers about how many connections and how much of a user's upstream bandwidth the Spotify client will use when streaming to other users; the Spotify client offers no way for the user to configure this.

In May 2010, Spotify introduced "Unlimited", which allows one month of unlimited, advert-free playback for half the price of Premium; however, it does not include any of Premium's other special features.

In October 2010, Wired reported that Spotify is making more money for labels in Sweden than any other retailer, "online or off".

During 2010 Spotify paid more than €45 million to their licensors.

In March 2011 Spotify announced that it has one million paying subscribers across Europe. In September the number of paying subscribers doubled to two million, or at least €10 million per month of revenue.

According to About.com, independent musicians can easily distribute their music to Spotify; pay for paid downloads is $.70 USD, pay for streamed songs is on a sliding scale basis determined by the total number of monthly plays an artist receives.
