Warrior is simple and effective. Almost a bit too simple, but I reckon the music itself will build on the title and its themes enough to my satisfaction. The lack of pretension Ke$ha brings to the table is refreshing. All we know is that she'll give us fun tracks, that hopefully aren't complete club garbage with a positive-leaning (that also hopefully won't translate into schmaltz).
ARTPOP is something we'd expect from Gaga, since she's used different permutations of the term ever since The Fame era. True to Gaga-form, the title implies a whole lot that, at this point, we're not so sure the music will be able to deliver in any meaningful way. I hope she'll just let the music do its thing and not weigh the whole record down with explanations and retreads that plagued BTW.
