In what could only be interpreted as a way to stay at the top of the music subscription heap, Spotify has announced that it will allow Android and iPhone users to stream music absolutely free — with a catch.

The catch is that users won’t be able to stream music any way they choose. Instead, this free Spotify mobile streaming will only let users play content in a shuffle mode.┬áThe move mirrors offerings from rival services like Pandora.

Updates to enable the free music streaming are already available in Google Play and the iTunes App Store. Spotify does have a Windows Phone application, however it appears users won’t be able to stream content through that app.
