What is the No. 1 song of 2017?

Despite the historic feat of the song "Despacito" which stayed at No. 1 on the US music charts for 16 straight weeks, the song "Shape of You" by British singer-songwriter Ed Sheeran has been tabulated as the biggest song of 2017, according to Billboard magazine, which ranks the popular songs in the US and elsewhere.

Released on a digital download on January 6, "Shape of You'' continues to enjoy massive popularity as it stays on the US chart at No. 25 for 48 weeks now.

In September, "Shape of You," which was written by Sheeran with pop superstar Rihanna in mind, became the most-streamed song on Spotify with more than 1.32 billion streams.

At No. 2 was "Despacito" by Luis Fonsi and Daddy Yankee featuring Justin Bieber which earlier tied this year with "One Sweet Day" by Mariah Carey and Boyz II Men for the longest-run at No. 1 for 16 weeks in the 59-year history of US charts.

"Despacito" is up for "Record of the Year" and "Song of the Year" at the 60th Grammy Awards which will be telecast live from Madison Square Garden in New York City on Jan. 28, 2018.

Sheeran, who was earlier forecast to dominate the 2018 Grammy nominees, only notched two minor nominations - Best Pop Vocal Album and Best Pop Solo Performance.

Critics said that Sheeran's non-appearance on four major categories at the 2018 Grammys was one of the biggest surprises and snubs among pool of major honorees

At the 2016 Grammy Awards, Sheeran won Song of the Year for "Thinking Out Loud" and Best Pop Solo Performance for the same song. He also received a nod for Record of the Year.

In January, Billboard refreshed its readers on how the Hot 100 chart works.

"Generally speaking, our Hot 100 formula targets a ratio of sales (35-45 percent), airplay (30-40 percent) and streaming (20-30 percent);"

"Of course, that's an overall target for 100 songs each week. That mark can change week-to-week. This week, though, the Hot 100 breaks down in line with the formula's intent: sales, 39 percent; airplay, 34 percent; and, streaming, 27 percent;

"And, week-to-week, some songs show largely along those percentages, while others skew noticeably toward any of the chart's three metrics."
