Each user of my app will have anywhere from 10-1000 known songs, and will accumulate more throughout the life of their account. There is some overlap, but for the most part, each user has a unique library of their own music.
I see that Echo Nest's dynamic playlist methods can be instructed to choose from a catalog. Can I use Echo Nest to specify each users' library as a unique "catalog" and generate streaming radio/playlists with the contraint that playlists only be composed of songs found within that users' library?
Thanks for your time,
