A pronunciation issue
I realised that in Latin the letter "v" is pronounced "w". Yesterday, when I was listening to the song "Ave Maria" & suddenly felt that singing "A-wei Maria" would sound quite funny & almost unbearable. Does this happen to anyone else?
Classical Latin pronounces it like a w. Ecclesiastical pronounces it as a v.
I first learned to sing Latin with Ecclesiastical pronunciation, but eventually switched to Classical because that was my personal preference. If you'd rather do the opposite, then that's your choice - it's just a matter of style. :)
P.S. Awei isn't quite accurate. Aweh (without the upwards swoop on the e) is more accurate. :)

Latin here is pronounced totally differently from the way I first learnt it anyway - but as I'm never going to speak it I just turn off the audio and hear it my way in my head....
But, I do know that ecclesiastical Latin is pronounced differently from classical Latin. I'd guess that's your difference.
