By the Way

Much of the lyrics are simply fun wordplay by lead singer Anthony Kiedis, but it does talk about a girl named "Dani," who was the "Teenage bride with the baby inside" on the Red Hot Chili Peppers 1999 song "Californication," and also appears in their 2006 song "Dani California." Kiedis says that "Dani" is a representation of every girl that he's come across in his life.

"Waiting 4," an electro-house track by Peter Gelderblom, became one of the most popular songs in clubs worldwide during 2007 and peaked at #29 in the UK singles chart. It was based heavily around a sample from "By The Way," and The Red Hot Chili Peppers enthusiastically approved its release despite their usual hardline stance on the use of their music in samples.

This song did very well in the UK, where the group's funkier fare is embraced. Along with "Dani California," it's one of their two song to reach #2 on the UK chart, the highest they've gotten. In America, their biggest hit is the ballad "Under the Bridge."
