If they'd done this 4 years ago they'd have a smash on their hands! I find it hilarious how they collabed though, since Mr Saxobeat sounds just like an Inna song (mixed with Alors On Danse). A bit redundant for them to do a song together, it's like when Pitbull and Flo Rida collabed.
Romanian house music is basically what Inna and Alexandra Stan (minus her most recent album) sound like. A lot of it is redundant and repetitive. They are pretty popular in their respective genres though and I think the collab is definitely overdue. Excited either way.
