In February 2007 Helena Vondráčková was confirmed as having accepted the invitation of Česká televize (ČT), the Czech Republic's Eurovision (ESC) sponsor, to compete in Eurosong 2007, the national preliminary round for the Czech Republic in Eurovision 2007, the Czech Republic making its ESC debut at Eurovision 2007. Vondráčková was the only name which ČT confirmed as a Eurosong 2007 entrant prior to the official 15 February 2007 announcement of Eurosong 2007 entrants: this announcement stated that Vondráčková would be competing with a track from her 23 October 2006 album release "Zastav Se (...A Poslouchej)" entitled "Samba". Although the Eurosong 2007 final was not broadcast by ČT until 10 March 2007 the competing songs were made available for listening from the time of their announcement with voting - done by SMS - open from 23 February 2007: around the last-named date ČT announced the disqualification of "Samba" citing the track had been recorded too far in advance to be considered as a possible entrant for Eurovision 2007. Vondráčková, given the prerogative of competing in Eurosong 2007 with a more recent song, did submit the track "Ha ha ha" but soon withdrew from Eurosong 2007 citing her disenchantment with the winner being chosen by SMS voting.
