X is for X.

Apologies for the extended break but finally back to conclude this!

Two acts with an 'x' in their name released a single titled 'X' during the 00s to varying degrees of success. US rapper Xzibit took his track all the way to #14 in 2001 - becoming his biggest UK hit at the time. 5 years later and it's Liberty X's turn - releasing their track as the lead single to their third album (also titled X) in summer 2006. The track would break their string of 10 top 20 hits, peaking at an underwhelming #47, signaling the end of the band.

But which is your favourite X?
