It's definitely the same song. Following your link, I see that someone got in contact with Robin Jenssen of Dsign Music, who said he'd look into it and asked for Lenni's label etc. This implies that he knew nothing about the Lenni track, but it doesn't guarantee this. And in any event, though I'm not up on the law, as far as I know you don't have to have the writer's permission to do a cover, nor do you have to inform the writer. As long as you attribute the song correctly, and pay royalties to whomever you have to pay royalties to, you're legally clear.* So nothing's necessarily nefarious in Dsign's not having known their song had been covered.

But if Lenni or whoever simply lifted the song, keeping the same title ffs, what was she/were they thinking? If the track goes big, of course whoever owns the rights is going to find out. And if it doesn't go big, you've probably not made money anyway.

*Sampling, using parts of songs, altering songs, and so on, may be a different matter. I do suspect that a lot of producers just take what they want and decide that if and when they hit with it they'll go into negotiation, but in the meantime they don't want the time and expense of getting permission. But simply lifting a song doesn't make a lot of sense. Once again, though, I'll append the phrase "as far as I know."
