Music Aggregator

Music Aggregator is a Capturer of sorts, but uses information coming from other services to produce its result.

Configuration

Requires the IP and PORT of the Store, and a list of musical Capturers that are running.

Internals

The service must receive Artist Name, Album Name and Song Title. It aggregates information on all musical services and produces a count of each played song.

We keep:

• artist: Text.
• album: Text.
• song: Text.
• count: int, increases on each song send.

Also, we need to keep a list of capturers we receive per day:

• day: Day being generated.
• capturer: Capturer name.

The output is not produced till all musical Capturers send their information.

Output

{% for song in todays_songs %}
{{ song.name }}, by {{ song.artist }} played {{ song.count }} times.
{% endfor %}
