In this blurry zone between online interaction and the real experiences of live performances (like the ones we saw at One Love Manchester), a new generation of music stars and fans is emerging.
Grande also ushered in artists like Little Mix and Imogen Heap, while Stevie Wonder was featured in a video segment where, while strumming his keyboard declared, "Love is truly the key, I don't care what ethnicity you are, what religion you are".
After all, the performance was being live-streamed across the world so will.i.am could have been addressing London.
The producer/rapper was quick to quash the rumours that he mistook Manchester for London.
Fellow singer Miley Cyrus joined the rendition and said: "I'd like to wrap my arms around each and every one of you and thank you".
All proceeds from the concert went to the We Love Manchester Emergency Fund which was set up by the City Council in partnership with the British Red Cross. She sang My Everything with students from Parr's Wood High school in Manchester, comforting 12-year-old soloist Natasha Seth when she was overcome with emotion.

With only so much room on the bench, it appears that Clarkson could end up being the odd man out. Alford also talked about his former point guard and what a phenomenal player he was.
"It's very important. We need to stand united against it now. All we feel here tonight is love, resilience, positivity", Williams said.
Towards the end, Grande got emotional as she sang a heartbreaking version of "Somewhere Over the Rainbow" to close out her benefit gig.
"Seeing you guys coming together was a sight to behold, we love you, we are with you, the whole world is watching", he told the crowd.
Grande surprised young fans injured in last month's attack with a visit to the Royal Manchester Children's Hospital on Friday.
Grande was all about love during the concert as her 25-year-old boyfriend Miller joined her on stage.
The concert seemed a philosophical success, too, as Grande played host, criss-crossing the evening's lineup of musicians, all of whom pleaded the case for solidarity and love.
