“Mood Ring,” a sexy, atmospheric bonus track available exclusively on the Japanese edition of Britney Spear‘s Glory, has been leaked. DJ Mustard produced the track, which didn’t make the cut of Glory‘s US version – I don’t know why, it’s GORGEOUS – but appears as part of the album’s Japanese package. Industrious Britney fans collected snippets of leaked audio and seamlessly cobbled them together for all to enjoy. Listen to it below.
