My all-time favourite songs are:
Westlife - When You're Looking Like That, World of Our Own, Queen Of My Heart
Oasis - Songbird
Mud - Tiger Feet
The Beatles - Twist & Shout, Please Please Me (closely followed by There's A Place)
Queen - Bohemian Rhapsody
Not sure what that says about my music tastes, I tend to just get automatically judged because of my love of Westlife. :P I love a lot of music though, I like the variety.
