Some people do apparently still not there are songs that are published in different countries at different times. Danza Kuduro was here in Germany this year published (in connection with Fast5) and can also count on the summer hits 2011 thus. Last year it was similar to "Stereo Love" by Edward Maya, which also ran in other countries in 2009. The other reviews also complain about the version of the song with Don Omar. The original version appears to have been well with Big Ali, which it so to make repeatedly economy still good songs badly. That may be a matter of taste: If you like silly pure cry is thus certainly better served (ok, there is also a part of the really sounds quite nice and in the version with Don Omar is not with) Best easily compare on Youtube or so the two versions.
Conclusion: In addition to "Mr.Saxobeat" and "Welcome to St. Tropez" the summer hit this year.
