Sunetti won on its first participation with Nina Zilli's song "Per Le Strade" and therefore hosted ISC 04 held in Affetto. Interstat 2012 Q2 showed that 207,181 people emigrated to Sunetti, the highest immigration level in Sunettian history. This was supposedly due to Zilli's success in ISC 02. There have been two cases in which Sunetti did not qualify for the final: Firstly in ISC 16, again in ISC 18 and once again in ISC 25. Regardless of its three non-qualifications, Sunetti remains one of the most successful countries in ISC in terms of qualification. On average, Sunetti scores mid-table in the final. In fact, a total of 9+ entries were placed between 11-15th place in the grand final.
Festa della Sunetti is a monthly music festival organised by Sunettian public broadcaster Channel of Sunettian Isles (CSI). It determines the country's representative for the Internatia Song Contest since its debut in the 2nd edition. It Sunetti's second most viewed national music show, behind the show, "Cheers to the Hits", which reveals the best mainstream hits all around Internatia. Keohretcha 23's "Rainmaker" by Emmelie de Forest is the only non-Sunettian ISC song to ever be #1 in the Sunettian charts.
Every Sunettian entry for ISC has been selected through Festa della Sunetti. The festival used to be open to all of Internatia to vote it, but due to budget cuts by the CSI, Festa della Sunetti sometimes televise the show in Sunetti only.
