Why do আপনি like the Rin/Len's voices?

For me, Rin and Len's voices are very hit অথবা miss.

First of all, Japanese is my সেকেন্ড language, so their not-so-good quality is really noticeable. Neither of the voices sound very natural. It's actually a little endearing.

They also have very strong, sharp voices. Both of them are like that. They sound off in a lot of softer songs unless someone uses an Append.

Though one reason why I like them so much is because they work well with genres I like. It's obvious when আপনি look at my সঙ্গীত collection that I like hard rock, and their voices are great at standing out and overpowering the loud instrumentals. NatsuP is one of my favourite producers because of her rock music, and she can tune both of them beautifully. Not to mention that both can sound great in jazz songs if they're tuned well and are গান গাওয়া in lower registers than they're usually in. I really like jazz as well, so it's great to hear a higher voiced Vocaloid sounding good in it. It's usually the altos that sound nice in it.

I don't know, those are just my মতামত on their voices. To be honest, the quality of their original voices is probably why neither of them are favourites for me.

I actually don't like Rin's voice all that much, but she sounds really good with those happy, fast songs. Len, on the other hand is a lot আরো appealing to me. his voice sounds quite soft at times and bright at others, oh and I think Len can pull off sad songs like Servant of Evil and stuff like that better than Rin. While she is better with happy songs like I Like You, I প্রণয় You.
Then again, this is just my opinion.
