Pyjama is an (unofficial) client for Jamendo, the free music community. It helps you to browse through Jamendo's database in order to find new albums. You can stream the music, create playlists, sort the albums by rating and tag, rate each track, and star albums you like most. An integrated Firefox instance helps you to interact with the Jamendo community.
Squarebase is a Web-based interface for MySQL databases. The basic idea is that it builds a database (called the "metabase") that describes the structure of the database. The information in the metabase is used to format lists and forms for browsing and editing the contents of the database.
