Simple Spotify 'Add Tracks' To Playlist

This is an easy job for a detailed person who can follow simple instructions.

I have a spotify account (logins will be given to winning person) that I want to add a list of 500 songs to.

This will involve:
1 - Take each track and artist from this list: http://www.time1075.net/top-500/

2 - Login to Spotify account (once) and search one at a time for each of the artist and track (ensuring ONLY the original artist is added - for any you can't find e.g.: The Beatles create a text file with them in)

3 - Once found add to the already created 'Top 500' List in the spotify account

4 - Thats it!

I estimate it should take around 4 -5 hours.
