When Kanye West first started on his upcoming album, it was going to be titled So Help Me God. Somewhere along the line, possibly inspired by Kim, the title was changed to SWISH. Over the past year, we've grown accustom to that being the name, but 'Ye has other plans. He's once again renamed his eighth album.
New album title, WAVES— KANYE WEST (@kanyewest) January 27, 2016
As to why he decided to change it, there's no official explanation besides the fact that one of the songs on the album is titled Waves. Maybe he was sitting in the studio vibing out to the album and just really loved the song. Who knows, it could change again tomorrow. One thing's for certain: Kanye's opinion of what he has created is through the roof:
