NBC’s “American Song Contest” series premiere was topped by a new episode of ABC’s “American Idol” on Monday, according Nielsen data.

The two-hour debut of NBC’s U.S. adaptation of the European mega hit “Eurovision Song Contest” averaged a 0.5 rating among adults 18-49 and 2.899 million viewers while airing live from 8-10 p.m., per Nielsen’s official national ratings, which are time-zone adjusted. Meanwhile, “Idol” averaged a 0.7 key demo rating and 5.289 million viewers during that same window.

“American Song Contest” is a live show for the East Coast, but airs tape delayed for the West Coast.

Hosted by Snoop Dogg and Kelly Clarkson, the all-live “American Song Contest” features 56 artists representing the 50 states, five U.S. territories and the nation’s capital, all competing for best hit song. A combination of public and jury votes will decide who will advance in the competition, with the jury being comprised of 56 people, one representing each state/territory, who are a mix of music industry executives, songwriters and radio programmers from various genres, as well as managers and members of the Recording Academy.

“American Song Contest” will include three rounds, taking place over eight weeks. The “Qualifying Rounds” will have 11 acts in each episode (with one week featuring 12). 22 artists will perform in the two-part “Semi-Finals” with the Top 10 performing in the “Grand Final,” where a winner will be crowned. Voting for the qualifiers opens on Mondays and closes Wednesday mornings.
