streamtagger is a self-hosted cloud music player and associated utilities focused on sharing music and ideas about music with trusted friends. The main viewer is a Python-Flask app which stores music files on the local file system, and stores site information and cached music metadata in a PostgreSQL database.
On the back end, streamtagger attempts to store information about a particular music file in the file itself, generally in ID3v2 tags. This functionality is currently not fully working (see issue #4), but when it does, it should be possible to almost fully reconstitute a streamtagger site (including database) with just the folders of music files along with new passwords for each user.
To bring up your own system, see the system documentation.
The root page displays and enables playing and/or editing tags of all music. A particular song or songs by an artist can be found at /songs/<partial name of song or artist>, or a specific song can be found at /songs/<partial artist name>/<partial song name>.
Song tags are at the heart of streamtagger; they enable users to attach useful information to songs and then later view, sort, and filter via that information.
A list of all defined tags can be found at /tags and the values for those tags can be displayed on most song-listing pages by using the show URL parameter, separating multiple tags by commas (e.g., http://localhost:5000?show=letsdance,latenight). Because tag values are per-user, the tag value given by a specific user can be viewed (and edited, if the user is logged in) by prefacing the tag with username@; e.g., http://localhost:5000?show=ben@letsdance,lucy@latenight.
To limit songs displayed to only ones with certain tags, use the hastag URL parameter in this form: ?hastag=[username@]tag1name[=tag1value]. So, for instance, to see songs that anyone has tagged with any value in the "letsdance" tag, ?hastag=letsdance. To see only songs that are rated a 5 for the "letsdance" tag, ?hastag=letsdance=5. To see only songs that ben has rated a 5 for the "letsdance" tag, ?hastag=ben@letsdance=5.
To match any one of multiple conditions, append additional conditions with a | character. For instance, to see only songs that have some value for "justlisten" or a value of 5 for "latenight", ?hastag=justlisten|latenight=5. To match every one of multiple conditions, add additional conditions with additional hastag parameters. For instance, to see only songs that are rated a 5 for "letsdance" and a 5 for "latenight", ?hastag=letsdance=5&hastag=latenight=5.
The upload form can be found under the + menu on the root page. Currently, only MP3 and unprotected M4A files are supported, and M4As will be converted to MP3s before long-term storage.
Additional users can only be added by the admin user at /users/admin. Upon first-time UI execution, an admin user will be automatically created by the UI and the password will be stored in a file in the UI container. This password can be printed to the console with print_admin_password.sh, but it will disappear when that container is destroyed. If this password is lost, the password hash can be manually set directly in the database through adminer. The algorithm to compute the hash can be found in login.js and can be executed using an online SHA1 calculator by manually constructing the string to encode. For instance, for username "ben" and password "notsecure", the text to hash would be K80Tgi^w1&jcbennotsecureK80Tgi^w1&jcben and the resulting hash should be d3c477fa4eb121d839c9e499f7ec770ff77ce458.
StreamtaggerSync is a simple .NET application that automatically synchronizes a set of music from streamtagger to a local computer, and also creates playlists according to specified filters/queries.
