As I posted on the last episode, I like the new OST pieces, precisely because they are different.

They are different enough to give a different feeling to the main series and yet similar enough to make you (or at least me) still feel a connection, which in my opinion is the perfect tone. Similar, but yet different, since despite the way it's aired Fairy Tail Zero is a spinn-off series and not truly part of the main Fairy Tail series.

I hope when Magi eventually comes to the Alma Torran arc, they do something similar with their OST... even though for Magi the long flashback was done in the manga itself rather than a spinn-off like Zero.
