Rhythm is a Dancer is a cover of Snap's older song in a more cascada-ish style, and i personally like it fairly much, it is very different from the one you mentioned.

I used to be a huge fan of this - i still listen to it every now and then.

A few things i'll say - every new release is a cover, with very few examples. there used to be a minimum of creativity in the genre, but it has faded away. at the top of the genre are such people as DJ Manian (producer of cascada, as well as a lot of other things) and Rob Mayth. Also notice the fact that most songs from the same producer uses the same samples, same basslines, same leads, same everything. A vast majority of the newer producers are just copying the "styles" of the aforementioned.

anyway, here's a few songs that aren't that bad:
Alex M. vs. Marc Van Damme - Technodisco (DJ Digress Remix)
Sven-R-G - Going Crazy
DJ Yanny - Rhythm Is A Dancer
Verano - You're My Angel
C-Bool - House Baby (Verano Remix)
Rocco & Bass-T - House Time
2 Vibez - I Believe
Pattern Mode - Citybeat (Tune Up! Remix)
