aflatune

Aflatune v1 was a 2010 music-discovery startup - tracks, albums, artists, playlists, comments, tips, and a similarity-driven recommendation layer, all wired end-to-end on a period-accurate Rails 2.2 stack with vendored Rails, Sphinx full-text search via Thinking Sphinx, S3 for audio assets, and a role-based authorization plugin. The model graph (~27 ActiveRecord classes) reflects a working recommendation and usage pipeline rather than a scaffold.

It was a real shipped product with the full early-Rails toolchain assembled and operated - mailers, observers, role-based authorization, and a browser-driven test suite alongside the standard Rails test pyramid (unusual for the era). Archived in mid-2010 and superseded by a v2 rewrite.
