Spotify, the music subscription service that has been so popular in Europe, is now available in the United States. Spotify offers users the ability to stream limited hours of music for free or stream unlimited songs for a small fee, from a library of over 15 million songs. And while it has a Spotify API out of the gate, it comes with a catch.
Think the social web is big? When it comes to connecting Twitter, Facebook and others to the rest of the web, APIs are there to do the heavy lifting. The category continues to explode, already surpassing the number of social APIs added last year. Our directory currently lists 558 social APIs, with nearly 200 added this year.
