Nickelback: How You Remind Me (2001)

Nickelback's "How You Remind Me" was the last rock song to hit #1 on the charts until 2012. It hit #1 in 2002 and was probably the #1 song of the 2000s despite the overall decline in rock n roll. The song was also the most played radio song from 2001-2009. The song is about a man haunted by his ex-girlfriend and sees her wherever he goes.
