Once Terraria 1.4.5 is released the pack will get another update adding new music for any new tracks added and potentially new replacements but as of now I don't feel the need to change anything around

Touhou 19 Update!

If you wanna listen to the new tracks you can find a sound test world in the description!

- Added Aether biome track (UM Stage 6 Theme - Lunar Rainbow)
- Added all new extended versions for all tracks in order to lessen the amount of pops that occur when specific tracks loop (pops are caused by a music pack glitch that has yet to be fixed as far as I know)
- Replaced a few tracks with new ones that I feel better fit:
- Eerie: EoSD Stage 1 Theme - A Soul as Red as a Ground Cherry (Replacement: DCC Stage 6 Theme - The Exaggerated Castle Keep)
- Corruption: GFC - Merry Magician (Replacement: IaMP Yukari's Theme - Night Falls ~ Evening Star)
- Crimson: GFC - Evening Dies on Dendera Fields (Replacement: VD Title Theme - Nightmare Journal)
- Alt Overworld Day: MoF Stage 1 Theme - A God That Loves People ~ Romantic Fall (Replacement: HSiFS Stage 3 Theme - Swim in a Cherry Blossom-Colored Sea)
- Day Remix: HSiFS Stage 3 Theme - Swim in a Cherry Blossom-Colored Sea (Replacement: UM Stage 3 Theme - The Perpetual Snow of Komakusa Blossoms)
- Queen Slime: HSiFS Stage 6 Boss - The Concealed Four Seasons (Replacement: HSiFS Extra Stage Boss - Secret God Matara ~ Hidden Star in All Seasons)
- Morning Rain: UM Stage 3 Theme: The Perpetual Snow of Komakusa Blossoms (Replacement: IN Staff Roll Theme - Eternal Dream ~ Mystical Maple)
- Otherworld Desert: AUSv3 - Sunfall (Replacement: AUSv5 - Eastern Strange Discourse)

- Fixed Music_43 (Ocean Night) and it now plays

- added a replacement track for Deerclops
The track is Loose Rain from Touhou 12.8 ~ [Great Fairy Wars] and in my opinion its a fitting pick but it's always hard picking tracks for bosses as there's lots to choose from. Hopefully you agree that this was a good pick!

- Fixed a small pop that wasn't fixed for some reason in the last update hopefully it's the last

if you find another one let me know and I'll fix it, thanks!

- Fixed a few tracks that had annoying pops at the ends of them and one that had an overly long pause at the end and beginning

- Small fixes
