Spotify Launches in the US With Facebook Connect but No Deeper Integration Yet

After years of anticipation, this morning the Spotify music streaming service launched in the United States with support of all the major record labels. The launch is the continuation of a partnership between Spotify and Facebook that could evolve into a special integration including prominent placement on Facebook. This alliance has the potential to threaten Apple, which chose to partner with Twitter for social integrations in iTunes Ping and iOS 5.
