Assuming these are the in-game counterparts to the Eorzean Symphony Album's, I think it's probably more worth getting the album. You get MP3 (26 tracks) and FLAC (10 of the 26 tracks). The orchestral arrangements are good. Not all are my cup of tea. But good.

Yes, it comes with 2 in-game orch rolls (not these same orch sheets on Mog Station) though I personally think it's weird to buy an item *just* for the freebie.

That said I do buy toothpaste sometimes for the cute mugs they bundle together. It's complicated. I'm an idiot.
