I recommend the Limited Deluxe Edition purchase. The bonus tracks are in fact really very good and absolutely no filler. In my opinion, they are even better than many of the tracks on the "normal" CD.
My favorites are: "Papi" (absolutely amazing at all on the CD), "On The Floor", "Good Hit", "I'm Into You" (What is) love "and" Invading My Mind ". The remaining songs are not bad, but not stay so truly in mind. The bonus tracks, however, are really very very good. Above all "Hypnotico" (hammer!) and "Charge me up". Also very nice is the Spanish version of "On the floor ".
