Slay Idol!

Will be updating this post monthly!

Kelly and Fantasia

I dare you to post live performances and whatnot and queen Angie Miller and God Haley reinhart would be in the top 10 !

I didn't include performances from Idol or studio versions from it.

Adam should be #2 by the end of this era (hopefully)

Yep. I'm sure he'll be #2. I'll update the first post with number of albums the artist has.

Kelly leading by over 250,000,000 views

Ofc the queen is slaying

Yasss

Deservedly the most viewed and the most successful

Kelly has more than the next 3 combined

Snatch that second place,Daughtry.

Queen Jessica only one above with only 1 album of Original Music with 5Million views

To all those asking
Haley has about 8Million views including Idol performances, without the Idol studios and performances, her original music won't reach 5Million. Angie's name is unsearchable, which means her original music views don't reach 1Million

Found these as well

Elliott Yamin 17,156,139
Allison Iraheta 11,798,049

mess @ since 2014

Goddess Clarkson slaying, as usual.

oops! Lemme add those! I don't think they're relevant anymore lmao, where are those views from?
