Nga, I totally agree that Rena Strober's voice is better, but I also feel this song is trying a bit too hard to one-up Lost in Thoughts, so in that aspect it can contend, but it does not come as easily. I sing a lot, and when I sing, I always sing Heritors of Arcadia, which means I always have to sing
A world riven by pride,
Repaired at last. (THIS PART)
And now (NOW always gets me) its makers can be at rest,
Our vision come to pass. (This is just the worst thing ever).
I have never cracked my voice trying to sing a song as many times as I did for this one verse. I feel this part rips out my vocal cords and puts them through a wood chipper. This one verse makes it not worth singing, because I know I can never finish the song, and that really just makes me sad. I never once had this problem with Lost in Thoughts.
As for instruments, I feel Heritors does so much with so little it really is impressive. The vocals match the instrumentals perfectly and create an absolute euphony. However, Lost in Thoughts is sang by one of the most beautiful voices I have ever heard. I am a boy as my profile states, and I freely admit than when I watched Rena sing on the video she posted on YouTube that I cried a bit because of how perfect it seemed. In fact just thinking about it makes me want to start again. Which almost never happens for anything ever. The instrumentals to Lost in Thoughts is very dynamic as well, and in my opinion far better. Heritors may do much with little, but Lost in Thoughts does much more without going overboard. And don't even get me started on Lost in the Waves. That song, I can't even begin to say how many times I have listened to the hour long loop of it on YouTube. Simply fantastic.
So yeah, I think Lost in Thoughts is better, Lyrics wise it fits the story with much more ease than Heritors, and in my brain there is no contest, I will always stand by Rena Strober no matter how Fate carries us.
Oh, and I like Heritors too. Just not as much.
