Eh, it's OK. It's trendy, but not tryndee... I can tolerate it, but it's nms.
This is all supposing
Cadence's spelled correctly, with the C. Word names should always be spelled as they are in the dictionary imo (excluding legitimate international versions), or else the name looks, quite frankly, illiterate to me.
I actually prefer
Candice over
Cadence.
Candice is very similar-sounding to
Cadence to my ears, yet is a much older, much less "lightweight" name to me.
