Not surprisingly, I completely disagree on the playlists.
I think to do justice to each year in the 70’s, you need 100 songs. If people don’t want to listen, skip anything you don’t fancy.
I’ve listened to 1970 in a couple of days this week while working. I enjoyed it very much.
I’ve already prepared my opening playlists for 1973 and 1975 and they have more than 10 songs and I am not changing them. If you want my narrative, which i have spent a lot of time on, they come with those playlists. Otherwise someone else can take those years and I will drop out of this.
