Playlist basics: As a rule, we play our newest music more often than the stuff we've had for a while. Some new songs get more spins than others due to the simple fact that we like some music more than other music. Other (not so new) songs may get added spins based on listener feeback, requests or whatever random mood Howard (program director) is in while crafting the playlist ... yep, a human person builds our playlist every week!
With the exception of the Full Playlist report, each report displays the Top 100 positions according to its specific parameters. Position ranking is determined based on a composite of spins and audience size. Although the composite score itself is not displayed (that's our secret!), the cumulative spins and audience for a given track/artist is listed in each report.
Top Tracks, Top Artists and the Full Playlist report show activity for the past week (Sun-Sat); the Fresh Meat and 30-day reports present real-time activity for the past 7 and 30 days respectively.
