Aww, no one likes the Strawhat version of We Are? That's kind of sad if you think about it. Though Personally I like the song itself over the opening, which was only filler.
Here's my list:
1. Crazy Rainbow
2. Brand New World
3. We Are! (2008 ver)
4. Jungle P
5. Hikari E
6. Kokoro No Chizu
7. We Are! -Mugiwara
8. We Are! (Original)
9. Bon Voyage
10. Believe
Yes, that's my #1, you Crazy Rainbow haters. And there is a good reason. When I first started watching One Piece subbed, they were almost done with Enies lobby–-the first subbed episode I ever watched fully was the one where Chopper had gone overlimit (I was like, 'who's that horned guy... and why is Usopp wearing a costume?'--I had only seen of 4Kids at that point so I did know the first 5 Strawhats..) I made my friend NOT skip the opening after he tried to pull up another episode, because I wanted to hear the opening song --I don't remember if the Chopper episode that he showed me even had that song as the opening because he kept showing me a slew of what he thought were the best fight scenes from different episodes. But from that day on I HAD to watch One Piece because it looked awesome to me, and that opening always struck a chord with me.
Oh, and just because I made a list of 1 to 10, doesn't mean I HATE any of the songs. I like all of them, just some more than others, and listening to Believe too many times in a row CAN give one a headache. Lol.
