Yes - Jamroom can create many different “indexes” or list pages that show everything from bands to users, songs, etc, even allowing you to create “Top” lists, artist directories, etc.
Generating the lists revolves around 2 scripts: ranking.php (Jamroom Ranking System) and newchart.php (Jamroom Advanced Charts - part of the Jamroom Bonus pack). The Jamroom Ranking system can create lists of bands, songs, users and stations, and rank bands, songs and stations based on the number of plays they have received.
The Jamroom Advanced Charts are similar, but take it a step further by performing daily tracking of song movements.
You can also modify the jamroom/templates/index/default_index.tpl template file - this file is the “index” file that is viewed by default when someone enters your Jamroom directory.
