Croatian cast of "Frozen" [singing voices]

READ FIRST!
OK, one very simple and fast video containing the names of Croatian singers in upcoming Disney's classic "Frozen" and clips of their songs. Croatian cast isn't spectacular nor impressive in any way. All those voices are new in dubbing-world, most of them I didn't know before. I heard only for Sementa coz she had one of main roles in musical TV series "Stella", but it's the only thing I know about her.
Nataša, singing voice of Elsa, one funny story about it/her (kinda): a couple of weeks I thought it was someone else, because there is another singer with the same name, only recently I discovered the "real" Nataša. And "our" Nataša was one of vocals in Croatian pop-band "Novi fosili" in 90s and that was ​​15 years ago and then she disappeared from music scene. So, Nataša's song in this video is from 1998, and I have no idea what kind a voice she has now. I hope she'll fit for Elsa now, coz she was (or maybe she still is) too sweat in those songs :/
As for guys voices, as I discovered: they are both performers in some underground rock bands, they don't have any dubbing experiences, and that's the only thing I know about them.
So that's it, nothing impressive, as I said at the beginning :/
