Pick your favourite song from each of your top 10 artists and put them in a playlist.
Listen through the playlist once a day.
When you feel you've gotten bored with a song, remove it from the list.
Rinse and repeat until only one song remains. This is the song that best stands the test of time.
Keep a record of how many days each song lasts for reference.
If after 100 days there is more than 1 song left, call it a draw! Any song that lasts that long deserves some recogniton.
