From the MLA Handbook (8th ed.):
1.2 Titles of Sources
Whenever you use the title of a source in your writing, take the title from an authoritative location in the work, not, for example, from the cover or the top of the page. Copy the title without reproducing any unusual typography, such as special capitalization or lowercasing of all letters.
As for italics or quotation marks, again from MLA:
1.2.2 Italics and Quotation Marks
Most titles should be italicized or enclosed in quotation marks. In general, italicize the titles of sources that are self-contained and independent (e.g., books) and the titles of containers (e.g., anthologies); use quotation marks for the titles of sources that are contained in larger works (e.g. short stories).
In other words, the styling used on the album cover is almost certainly not the styling used in its legal copyright information. But even if by some chance it is, MLA says to ignore that.
Also, the title of the album would be in italics, while the title of each song would be in quotation marks.
Therefore, the title of the album should look like this:
Good Kid, M.A.A.D City
