So what happened on the Real-Time Charts this week?

All Eyes on Ariana: Pop star Ariana Grande dropped her new single, “Focus,” and its music video on Oct. 30, and it immediately locked up several hours at No. 1 on the Trending 140. The sassy, horn-backed track is the lead single from the singer’s third album, Moonlight, due in 2016.

Despite its Oct. 30 release, “Focus” topped the Trending 140 three previous times thanks to a month-long social media countdown, in which Grande teased snippets of the track, and shared its cover artwork featuring the singer rocking platinum blonde hair.

Bieber Trifecta: Justin Bieber places not one, not two, but three entries on this week’s realtime chart as we enter the homestretch before his Purpose album drops on Nov. 13

First, Purpose’s second single “Sorry” maintained a strong presence on the chart, logging an additional pair of hours at No. 1. The pop superstar originally released the track on Oct. 22 with through a dance video featuring the ladies of the ReQuest Dance Crew. That clip – and the “Sorry” lyric video on Oct. 29, powered Bieber’s extended reign on the chart.

Meanwhile, a new release, “I’ll Show You” also clocked several hours in the penthouse after Bieber dropped its music video. The Skrillex-produced track features a pensive Bieber running around and playing in the midst of a majestic terrain.

And finally, the Canadian star paid homage to one of his countrymen, Drake, by releasing a remix of the rapper’s “Hotline Bling”…on an actual hotline. Bieber posted two phone numbers to his Twitter page on Oct. 30, and callers were greeted with Bieber’s remixed recording. The surprise helped out his pal Drake, whose “Hotline Bling” original redialed a stay at No. 1.

Why, ‘Hello’ There!: An unexpected, but highly anticipated release, gave Adele a huge command at No. 1 on the Trending 140 for much of the past two weeks. The singer released “Hello,” her first single in three years, on Oct. 23, and even just one day of advance warning was enough to gift Adele a lock on the Trending 140 on its release date.

As the Trending 140 began in May 2014, “Hello” becomes Adele’s first song to reach No. 1 on the Trending 140.

As “Hello” marks Adele’s first studio single since the blockbuster album 21, consumers gobbled up the new release, pushing the song to a record 1.1 million downloads in its first week, according to Nielsen Music. The song’s enormous sum easily powered it to a No. 1 debut on the Billboard Hot 100, Adele’s fourth chart-topping song. The record-breaking track previews the singer's third album, 25, due out Nov. 20.

The Trending 140 chart measures the acceleration of conversation around artists and their music, while the Emerging Artists chart measures the volume of tweets around new artists and their songs.
