Glutamine is now on Spotify. You can follow his link on twitter, which will lead you to the Japanese website, but you can also register in your own language. (There’s a code mentioned in Glutan’s tweet, but it’s a Japan-only offer)
If you don’t know Spotify, well, it’s a service that allows you to listen to your favorite artist songs (yes, even the ones exclusively on his albums!!) for free! All you need to do is to install Spotify (it launches after you register), and type “ぐるたみん” in the search bar. Then, press play!!
I don’t know if it’s better for his stats if we follow Glutan’s link so here’s a tutorial to register from the invite link under the cut.
