Would this not be more logically placed earlier on in the article (ie before 'Critical reception')?
"The song was performed live on American Idol" - what song?

"...along side earlier singles "Your Love Is My Drug" and "Tik Tok" on NBC's Today Show." - alongside is one word, the songs can be linked earlier in the section, but not in this sentence, NBC's Today Show can be linked to Today (NBC program), and the title should be italicised. Also note that it is called 'The Today Show' or 'Today', but not 'Today Show'

"In the performance she is seen" → was seen
