With the release of their "Greatest Hits" album in 2001, led by the single "Mayonesa", they achieved international success, which had previously been restricted to Uruguay and Argentina. This came following the move to Obligado Records and the opportunity to write their own material. The song became a hit throughout Latin America and Spanish-speaking North America, often referred to as one of the 'songs of the summer' of 2001. It reached #42 on the Billboard Hot Latin Tracks chart. Literally meaning "mayonnaise", it likens the sensation of falling in love with the process of making the dressing, namely beating your heart as you would mayonnaise. The song was accompanied by a catchy dance routine.
