I would question your sanity and your ability to reason.
I spent 57 hours and got the 100% ending...not sure where your 300 hour estimation is coming from. Compare X-2 to X and the game is not on the same level. The soundtrack had a few hits but NOTHING compares to X's (People of the north pole, back to Zanarkand).
I am glad you liked the game (I did as well) but it is not the best final fantasy, or best game of all time.
