The Rocktober Rumble tournament continues with a pair of acts who emerged in the early 2000s, made their mark and have consistently dominated the airwaves with their music.

Three Days Grace kicked off their One-X album with the driving rock single "Animal I Have Become," a song digging into the darker side of their singer at the time, Adam Gontier. The track went on to spend seven weeks at No. 1 in 2006. Take a listen in the player below.

That same year, Breaking Benjamin were continuing their uptick in their career with "The Diary of Jane," a chugging rocker from their Phobia album. It reached No. 2, but stayed on the charts for a good portion of 2006. Get a listen to "The Diary of Jane" below.
