My arrangement of MoF's Stage 1 theme. It's rather peaceful, and it definitely makes me think of autumn.

Touhou Project belongs to Team Shanghai Alice.
This song works best on any song that plays in an autumn-themed stage hack.
It's looped seamlessly.

Stage 3 theme from Fairy Wars, remixed for Oriental Sacred Place Volume 2. The background sounds are a little louder here than in the original version from Fairy Wars.

Marine Benefit's Stage 5 theme. It's very dance-like, and it's rather appropriate, considering Megumi's spells are dances themselves.

Marine Benefit is owned by Primary-Color Space (formerly nekofla).
This works on an aquatic or oriental stage hack.

My arrangement of EoSD's Stage 1 theme. It's quite an odd piece since the tuning of the original instruments ZUN used to make the songs of EoSD are noticeably sharper than the ones used in my arrangements.

Works best with dark stages.

My arrangement of Nitori Kawashiro's theme. To me, she's more cute than threatening, even with the machines. Because she seems to be a nice person based on her dialogue from MoF, I think being an ally to the heroine would suit her personality better than being an opponent of the heroine, which is why I thought she served a more purposeful role in SA than MoF.

My arrangement of the theme of Mystic Square's Extra Stage. The playing card enemies are so cute! Too bad I can't often see them behind all the bullets they fire. ;_;

My arrangement of LLS's Stage 4 theme. It has a nice retro feel to it. At the same time, it's ominous since Stage 4 is usually the first stage after the turning point, which is often Stage 3.

When I joined the site, I didn't expect to create many hacks. But, here I am, submitting my first hack!

Anyway, this is Suika's theme when you battle her in Scarlet Weather Rhapsody.

It loops pretty much seamlessly.

Touhou belongs to ZUN and Tasogare Frontier.

Enjoy! ^_^

My arrangement of Minoriko Aki's theme. It's a short, sweet and rather catchy piece.

My arrangement of Kogasa Tatara's theme. Poor Kogasa... Always trying to be scary, but always falling short of her goal... That's what makes her so lovable!

Yuyuko Saigyouji. Her utter naïveté easily makes her one of the most dangerous beings existing in Gensokyo. I mean, she just took spring away from an entire land just to see what her giant youkai cherry tree in her back yard would do if it were in full bloom! The most ironic thing is that the tree was basically her gravestone!
However, she is my second favorite character, the first being Kaguya. Her lovable gluttony from IN left me in stitches for at least 10 minutes total.

Track 9 of Changeability of Strange Dream
(Also remixed in the future to make CtC's title theme.)
This song is quite haunting, and I think it's one of the best songs in the album second to Phantasm Machine. I also see danmaq's thinking behind arranging this to make it CtC's title theme.

I don't own any games or songs referenced in these comments.
Try it on a title theme. I don't know which one would work best, though.
Custom looped.

My arrangement of IN's Stage 5 theme. This song, combined with the nauseating background and the nerves from four tough stages creates a recipe for disaster that Udonge's cards exacerbate... Well, that is to say if you're new to Touhou, aren't very good at it, or have severe motion sickness.

Marie's theme from Shuusou Gyoku. ZUN really made this one darker than before. I don't really see a happy circus when I think of this song. I see evil clowns instead...

I don't own this song, the original, or the sources of either of them.
Try this on a song in Luigi's Mansion.
Custom loop used. Best exemplified in preview.

Mima's theme from SoEW. I hear Magic Mirror in this quite frequently.

Mima's theme remixed by ZUN
If you have a hardware MIDI module, you'd be able to listen to this version of Complete Darkness in-game. I like the updated instrumentation, but I wish the tempo changes in this version were more true to the original.

I don't own this song, the original, or their source.
Try over "Giga Bowser (Melee)".
Loops perfectly.

My arrangement of the song that plays during the battle on the day of the feast in IaMP. ZUN described it perfectly himself. It does convey boiling anger, but it also portrays growing suspense. It's almost like the game's telling you, "Only a few more battles until you get to fight Suika!"

This is one of Reimu's themes featured in ZUN's first music CD. I think it was originally from Seihou and remixed for UNL. This one beats both of them because the EoSD-style instrumentation seems to fit this song best.

Touhou Project belongs to Team Shanghai Alice.
Try this over Mach Rider (Melee). I don't have it like that only because I wanted it to play in SSE. If that's the case, try it over whichever SSE song you see fit.
Had to give this one a custom loop since the original song didn't loop.

Marisa Kirisame's theme from PoDD. I think it's repeititve like Yumemi's theme, but for some reason, I like this song more.

My arrangement of the theme of Yumeko, the first blade-wielding ninja maid of the Touhou franchise! To be honest, I don't know why some people say Sakuya is a rip-off of her, because Yumeko can't freeze time.

As usual, I don't own the original song or the source of the song.
