Today is Sir Paul's 71st birthday, so this [Top 5 Tuesday] list focuses on his contributions to the Beatles' collected works.

This may have been one of my hardest [Top5] lists to date. Narrowing down all the Beatles songs to just McCartney's stuff was the first task. If you're unsure as to the authorship of individual tunes, check here for a cheatsheet. I narrowed down to a Top 20, then a Top 10. And seriously, cutting out the last five to make the final list was really hard. I barely even want to commit myself to this list (all lists are subject to change) but here's how I feel at this moment.

5 - Hey Jude


4 - Yesterday


3 - Let It Be


2 - I'm Down


1 - Lady Madonna
