ABC news has reported that:

In its November issue, which celebrates Q's 20th anniversary, the publication set out to identify the top 20 singles of the past two decades. Their picks range from pop sensations like Britney Spears' " … Baby, One More Time," and Outkast's "Hey Ya" to The Prodigy's punk/techno mix "The Firestarter" and Guns N' Roses' hard-edged rock ballad, "Sweet Child O' Mine."

"The thing about 'Smells Like Teen Spirit,' it was a watershed moment in rock music. It changed everything," said Q magazine deputy editor Gareth Grundy of the iconic Nirvana hit. "It put heavy music back on the map in the early 90's, really, that combination of punk-rock anger and the heavy Black Sabbath 70's metal. It was something new. Sulky kids everywhere loved Nirvana and continue to do so."

The songs were chosen by the staff of Q, and while the tunes have little in common, Grundy said they are all "instantly memorable."

"The song just basically had to be a good song," Grundy added. "We took a poll of all our writers and the staff of the magazine and we counted the vote and the list came in as you see it in the magazine."
