A friend of my challenged me to make a playlist with 100 songs by 100 different artists a couple years ago.
And it turns out it's actually quite a difficult challenge. It's tough to pick which are your 100 favorite artists and then select your favorite song by each, I have to say mine is still a work in progress. I'll post my latest update of the list here this week.
It would be interesting if we all did this and shared our playlists here. It's a great way to get a quick sense of each other's music taste.
