I think this is the coolest sounding word. I see it often in relation to self titled albums. Just a bit of trivia, George Strait's 27th album was simply named "George Strait" The quote from his website reads: "When asked about the eponymous title of this CD, George replied jokingly, 'Yeah, I ran out of CD titles so I just stuck my name in there'." :D
