Square Enix has made a piano collections CD for nearly every Final Fantasy game they've made. Well, not XII. That soundtrack sucked, and didn't lend itself to piano treatments. But the other ones are amazing. They take your favorite songs and give them beautiful arrangements by top-notch performers. If you've somehow missed these CDs, know that they're definitely worth tracking down.
Final Fantasy XIII soundtrack lends itself to the Piano Collections treatment nicely, so I've been hoping for one to be announced. Thankfully we've got word that one is coming. The guy behind the Final Fantasy X piano album is back for XIII. The release date is set for July 21 in Japan.
These usually come with sheet music in their final form, so I'm looking forward to learning some of the songs on piano too.
