1. Hero
2. Firefly
3. Sirius
4. Niji

.........AND We Can Make It! lol

songs that can help me when I feeling down?... ummm what's the different than first aid?...

anyway probably these:
-kotoba yori taisetsuna mono (my ever favorite arashi song! gives me a "homey" atmosphere, I love it, and always miss it when I'm not hearing it)
-take me faraway (more precisely Ohno's voice calms me down)
-we can make it (it's like telling me "you can make it, come on, don't be down, ganbatte!!"... ^^)

i feel like almost every arashi song is inspiring in one way or another ^^ but right now my most inspiring song is Pika**nchi Double. since im going through the time where youre almost out of university and figuring out what you really want in life, it helps to remind me that im still young and i cant let go of those dreams i have now or had in the past while im going through school. Sakura Sake is also one of my top inspirational songs since it encourages me to keep looking forward to tomorrow. This is what i really luv about Arashi and their music, they dont just talk about love and relationships, they talk about friendship and life and inspire and encourage me to keep going when things completly suck and i have no clue what to do. arashi is so great

Arashi really have a lot of inspirational songs compared to other groups..thats what i love about them!
my favs are:
1. We can make it!
2. Hero
3. Fight Song

"Your Song" is very inspirational. And when I'm running, I think Carnival Night pt. 2 gets me the most motivation

1) Happiness
2) Sunrise Nippon
3) Fight Song
4) Kitto Daijoubu
5) Right Back To You (not sure if this can be counted as inspirational or not but I do love it!!)

I love listening to Sunrise Nippon in the morning even though I don't live in Japan
