Pokémon Sleep has added more of its music to Spotify, with the release celebrated through outdoor advertising featuring Mew across Shibuya in Tokyo. The Pokémon official YouTube channel highlighted the campaign on Sept. 18, showing Mew freely flying through the city as part of the promotion. The Shibuya advertisements have now ended, but the newly available Pokémon Sleep music remains available to stream on Spotify.
