Well, it certainly isn't bad, not my kind of music, but it doesn't hurt my ears (some kinds of pop do, though).
While it's good that she writes her own songs, I think it's sad that this has to be concidered something special today... but it's a fact that most pop "artists" today are completely produced, in terms of beats and lyrics, so I respect her for writing her own lyrics (I doubt she does the beats)
And yes, it most certainly is danceable, but so are many other artists. I myself like Daft Punk for that matter.
