Today, Spotify made a big announcement – free mobile streaming. Starting right now, Spotify users who opt for the free tier can stream playlists and “shuffle” artists’ entire catalogs on their smartphones and stream any song they want at any time on their tablets.

As part of this announcement, Spotify also added the entire Led Zeppelin catalog. Hell yeah.

“Led Zeppelin and Spotify today announced that the band’s legendary Swan Song/Atlantic catalog is now available for streaming on Spotify. Nearly 45 years after the band’s groundbreaking debut album catapulted them to rock superstardom, Led Zeppelin’s full album catalog is now available to stream on-demand for the first time, exclusively on Spotify,” says the streaming service.

Spotify’s decided to make an event of it – releasing a couple of albums each day for the remainder of the week. Today you can stream their first two albums, Led Zeppelin and Led Zeppelin II.

Here’s the rest of the release schedule:

Thursday, December 12 – Led Zeppelin III (1970) and Untitled fourth album (1971)
Friday, December 13 – Houses Of The Holy (1973) and Physical Graffiti (1975)
Saturday, December 14 – Presence (1976) and In Through The Out Door (1979)
Sunday, December 15 – The Song Remains The Same (1976), Coda (1982), BBC Sessions (1997), How The West Was Won (2003), Mothership (2007), and Celebration Day (2012)

The last time Spotify made a big production of an entire catalog release was back in June with Pink Floyd.
