The song "I Got A Feeling" by the Black Eyed Peas is a good one. Another good song for a cheerleading dance routine is "Gold Digger" by Kanye West featuring Jamie Foxx.
'Girlfriend' by Avril Lavigne is good, as is 'Mickey' by Toni Basil. 'Hollaback Girl' by Gwen Stefani, or 'That's Not My Name' by the Ting Tings are also good.
It is all a matter of opinion. The recommended song for cheerleaders are songs with a fast beat, something upbeat. Techno is often a great choice for cheer leading squads due to its potential.
