Honestly after having listened to Glorious a lot it's really not a copy of Euphoria. Yeah it's somewhat similar but that's more an effect of the genre I think. I really doubt Cascada made that song after listening to Euphoria, and they had to audition like everyone else (I think?).
I'm surprised Romania didn't try to send Inna like they tried last year.
I don't believe they've made a copy on purpose, that would be just beyond stupid. But that they didn't realize how fucking similar the songs are amazes me. I mean when they peformed it at the pre-elections I was like: "guys, Loreen is backstage right now!" She must have been pretty bumbed.
