No "suppose" to it, Blue, song titles are simply not copyrightable. And that's from US copyright office. Matter of fact, there are many examples of copyrighted songs with the exact same names.

The US copyright office webpage FAQs even goes into detail about that subject, explaining WHY someone might not want to name their song exactly the same as another song that is already famous -- your royalties, if any, may just end up in the other guy's pocket!
