I like how they are open about this being B-sides crammed into a separate release. Honestly, I like this idea more than just bonus tracks on whatever edition.
However, they have 5 bonus tracks on the Deluxe Edition and 4 more bonus tracks on the Box Set edition. So 13 songs in total out of 26 new songs Mark will release in the following months, are bonus tracks. Let that sink in. So it's basically like 2 whole albums somehow were transformed into this marketing monstrosity. Half of the songs are bonus tracks. HALF!
UPD: Oh no, actually there are more bonus tracks as I counted "Going Home" as a new song. So 25 new songs, 13 of which are bonuses.
