Celine Dion turned to the public with an appeal to find original material for two new albums.
The 47-year-old singers request was "open to everyone" and aimed to discover fresh songs for a French offering to be released next year and another in English for 2017.
More than 4000 offers poured in via snail mail, social networks and in MP3 files from throughout France and other French-speaking countries.
They will be whittled down to just 25 by a panel of six French-language broadcast critics, fronted by Quebec music festival director Pierre Fortier.
"Naturally, out of the 4000 songs received, there aren't 4000 hits, but we've already found several good ones," he said.
