So I'm just wondering if there are actually two different versions of This is Me. I hear one version on the regular radio, but when I listen to XM radio and the song comes on, it's completely different.

Anyone have any answers?

Or where I can find the lyrics or the actual song of the 2nd version?

The second regular radio version is just without the 2nd verse. Its shorter for mainstream radio so they are more likely to play it.
