Okay so I'm trying to find my instrumental for Itsuka no Merry X'Mas and I can't find the original version that came on Songless but I do have the version pitched up to make it easier for a female voice that I found back when I covered the song solo. I'm going to keep hunting for the original version (I know it was a flac torrent of their discography that included it) but I'm going to upload the pitched version so you guys can hear the difference. (The only part that sounds weird pitched higher is the guitar bit right before the vocals start).
Edit: Okay, I can't find the original which is driving me nuts since I was the one who converted it from the .flac format and everything. Ugh. Anyway here's the version with the pitch altered to a higher key so it's easier to sing if you're, you know, not a guy. :P As none of us covering it are.
