I would also pronounce it dah-NAY. And I like it. I also like
Janae. I don't think it's too trendy at all.
On a sidenote, I discovered recently that I really like that "ay" sound at the end of a name or in the middle of a name:
DanaeJanaeReneeRaeMaeKaeJanaya
Mattea
But I think it feels trendy when that same sound is in the first syllable of a multi-syllabic name:
Jayden,
Caden, etc
Kaylee,
Hayleigh, etc
Shaylynn, etc
TaylorPeyton, etc
