Added the sample cover from the album store page:

I don't speak Japanese, but the page shows 【商品発送予定日は2017年4月25日(火)です】(April 25, 2017), so I'm wondering where the "May 04, 2017" release date comes from.
Also, it's probably impossible to tell until this is available, but anyone know if this has all the same music as the following release?
