And not just YouTube, but Spotify and iTunes and most other traditional methods as well. I've loved this band since I first discovered them in college back in 2005. The band just released a new album called Junk and it is available for free! So far, I've had 2 whole listens through of the album and I think it's pretty solid. Lots of the usual M83 synths and gradual buildups. Feels good to have them back in the playlist. :)
UPDATE: Looks like all of the albums from M83 are available on YouTube!
