This is my 3rd one of these, kind of a work in progress. The concept was to highlight debut tracks from said week's SiriusXM AltNation Alt 18 Countdown. I’ll also include some of the better tracks featured that week, while trying to not repeat them consecutively or too often (a tall order when, as you'll see from the notes, some of them have been charting as long as 15 weeks). It will always feature the #1 song (as the 8th track, for suspense) despite how many times it’s been featured.
