As a user, I want to see my Feed first after signing up/logging in, so that I can check out:
- Last added albums and tracks from followed artist user groups
- Last added playlists from followed user groups (NB handled from back-end: if they set their playlists as public)
- Last recommended artists from followed user groups (if they set their recommended artists as public)
- Latest news from Resonate
- If my Feed is empty, I want to be presented with a welcome message.
