1.0 music in future patches

[Enkidoh]

Definitely! Although I'd love to see more 1.0 tracks available on the Orchestrion as well, just having missing music from 1.0 like Navigator's Glory and Piece of Mind return would be amazing.

As a start, these are the tracks from 1.0 I would love to hear somewhere in ARR that have not yet returned:

Navigator's Glory ~ The Theme of Limsa Lominsa - self explainatory, this was the original city theme for Limsa Lominsa in 1.0. It was also the very first piece of music I ever heard for FFXIV 1.0 back when it was first announced at E3 2009, as it was used in that original trailer there.
Born of the Boughs ~ The Theme of Gridania - again, exactly what it says on the tin this was Gridania's original city theme in 1.0, and I still miss it.
Emerald Labyrinth - the original zone theme for the Black Shroud in 1.0, later in 1.0's life it was changed to only play in deeper parts of the forest.
The Forest's Pulse - the 1.0 Black Shroud battle theme
Widdershins - the 1.0 Thanalan zone theme that was added later which played in more higher level parts of the zone, especially around Zan'rak and Little Ala Mhigo
Holy Consult - a cutscene track that was often used for scenes involving Ishgardian npcs, I assume this was also planned to have been eventually used as Ishgard's original 'city' theme, but naturally that never happened.
The Seventh Gate - battle theme that played during certain instanced duty battles, it's cues to FFVII's Still More Fighting were obvious
Tears For Mor Dhona - Mor Dhona's 1.0 zone theme, this spooky music still makes me break out in goosebumps every time I hear it. It just fitted the zone perfectly
Phantoms on the Lake - Mor Dhona's 1.0 battle theme, I would love to see the full track return though, as an abridged version appears in ARR that was used in the Lost City of Amdapor, known as 'Persistence' on the Before the Fall album, but I would still love to have the full track return as well.
Piece of Mind - a cutscene track that appeared when arriving in your starting city in 1.0 as well as when choosing the Path Companion, this is probably the 1.0 track I would love to see come back the most as it is my favourite FFXIV 1.0 track (next to Answers of course ).

Phantoms on the Lake - Mor Dhona's 1.0 battle theme, I would love to see the full track return though, as an abridged version appears in ARR that was used in the Lost City of Amdapor, known as 'Persistence' on the Before the Fall album, but I would still love to have the full track return as well.

Likewise. I actually really hate (not dislike, but hate) Persistence due to how horribly repetitive it is. It's the only music I mute in FFXIV (if given the chance). By the way, missed opportunity with Keeper of the Lake's music. They could have had Tears for Mor Dhona play as the dungeons main theme and have Phantoms on the Lake play as the mini-boss theme. Would have been perfect.
