Der Spiegel reported that Twitter was concerned about SoundCloud not having licensing agreements to stream copyrighted material.

Twitter is rumored to be buying SoundCloud, but if it changes too much, it could break the backbone of the music service.

Facebook is rumored to announce its deal with the Sweden-based music streaming company Spotify in August at its annual developer conference f8.

Spotify, the popular European online music service, has told record labels it will cut down the free music it allows users to access without a paid subscription, according to people familiar with the plan.

Online music sites are still around and still popular, as seen by the latest investment into SoundCloud, a Germany-based file sharing service.
