Last year, Lady Gaga's 'Bad Romance' was crowned the Best UK #1 of 2009, now we've opened the search to find 2010's Greatest Song. You can nominate up to FIVE songs that have been a UK Top 20 Hit from Saturday 2nd January, to Saturday 4th December.

Unfortunately, this voting will only be open to people from the UK or Ireland to give lesser known British and Irish acts a fair chance of winning.

All of the UK's 2010 #1s are automatically entered, so no need to nominate them.
