with the digital release being first if not exclusive, it hasn't had to be on a tuesday. an independent artist or label can release an album whenever on whatever platform and to whatever stores. even some major labels got in on that (the advent of the surprise album). if you buy physical releases online, preorders ship and may arrive before the release date, imports are out on different days of the week, etc. even brick & mortar stores, including the big boxes, have had new release days other than tuesdays some weeks, especially around a holiday. i loved new music tuesday growing up and fondly remember listening to what would become my favorite albums on their release date, but times change, partly because that excitement consumers had is largely gone.
