Hello, i've tried to do a catalog-radio static playlist but each time a new playlist is created it is just taking one artist from the catalog as the seed, not all them. This is the what i am doing:
I have this artist catalog: http://developer.echonest.com/api/v4/catalog/read?api_key=SBLWTA99PCG4NJOYG&id=CAUOLDM1405EB36E5E
I create a playlist: http://developer.echonest.com/api/v4/playlist/static?api_key=SBLWTA99PCG4NJOYG&type=catalog-radio&seed_catalog=CAUOLDM1405EB36E5E&results=100
I wonder if there is something i am missing. Thank you very much!
