These three artists are ambiguously similar to Enya, I think...
The song by The Beautiful South - Rotterdam (Or Anywhere) has been in my head today
Maybe it's the quirky lyrics (much more subtle in some of Enya's songs, like My My Time Flies or Anywhere Is) ?
It sounds okay to be mixed with Enya's Someone Said Goodbye/the remix
(this)
This 2022 performance by Paul Heaton and Jacqui Abbot; singing still sounds great

A 1996 song almost predicting the 2020s Eurovision host cities "Rotterdam or anywhere, Liverpool or Rome", haha
I thought this was a song written by Rod Stewart, but that's a cover too (
this was the original)
Amy Belle was busking in Glasgow in 2004 when Rod Stewart found her, and she got to sing 'I Don't Want To Talk About It' with him that evening:
Her voice is different to Enya, but Amy Belle's music video for 'Didn't I Say' is a somewhat more wild copy of 'It's In The Rain'
-see this 
I saw some rather good buskers in Glasgow, 2014 (as well as some athletes for the Commonwealth Games that year)

I quite like Scottish singing voices
With all due respect, why is Tracey Thorn on the cover?
Haha, I see the similarities (it was
this AI-generated image of Enya that I used for the 'Moonbow' concept

) , more so when she had dark hair.
I don't think I'd heard of Tracey Thorn before this mention, but glad I know of her now

Here is her cover of 'I Don't Want To Talk About It':
(Similar suit style in the late 80s

see this mashup
'I Tomorrow Want To Talk About It' 
)
Yet to listen to more music from Everything But The Girl and other Tracey Thorn songs, but they are really interesting from what I have heard so far, and she has a nice voice, even with age. I saw the music video for 'Sister' from 2018, and also just saw that EBTG is returning (rather soon, with a new album on 21st April!)
Hope 'Fuse' does well! (and it would be great if Enya also releases some new music this year too)

Random extra thing, I liked seeing the 1983 archive footage on the main ETBG YouTube channel

(It would be interesting to see something like that on the enyatv channel, such as random early footage of the Enya trio

)
