Well, so far she's released 3 songs in 2016, Namie has released 4 so it's not a bad thing...? She's just behind the own pattern she set of always having a summer release, but maybe SUMMER of LOVE intended on ending this chapter of her career? Like, I don't mean she'll never do a summer release again, just that she doesn't feel the need of doing a maxi single every year anymore.
I guess we'll get some new music by the end of the tour or until December (I like the theory of the 17th anniv tbh), so for now I'll focus my energies on new songs from BASTILLE and OneRepublic and relax a bit on Kuu
