A lot of problems with database access.

The application is read-intensive and there is no need to maintain join tables. Use them as KV store.

App

Album table
EpisodesByAlbumId Map<albumId, List<episodes>>
ProgressByEpisodeId Map<episodeId, progress>

Server

Fave Map<userId, List<AlbumId>

For global variables, subclassing instead of singleton.

Other than database access, the biggest issue is the list rendering. We should get back to ViewHolder pattern. And the downloading view dictionary design is not scalable.
