I've been mulling over a couple posts on how kids music has infiltrated my "regular" world. To begin, let's take a look at my iPod. It's an iPod Shuffle, actually, the first generation, with -- OMG! -- a full 1 GB of storage, enough for maybe 300 songs if you like blissful (and short) pop songs for your 5:30 AM jogging or workout pleasure. At the moment iTunes says I have 313 songs on my "Workout" playlist, or about 1.03 GB. In assembling my playlist, I need to be cognizant of the fact that my wife will sometimes use my Shuffle. The upshot of this is that the playlist is devoid of Nirvana (wife: not really a Nirvana fan) and a lot of somewhat harder-edged tunes I might otherwise put on the playlist. My playlist is, aside from that caveat and the absence of workout-unfriendly string quartets and Miles Davis, fairly representative of my overall collection -- 21 TMBG songs, 12 U2 songs, 11 Spoon tracks, 10 from R.E.M., and so on. There are also in those 313 songs a total of 31 songs -- almost exactly 10% -- I'd classify as "kids music" (iTunes' categorization isn't the best -- it puts some Elizabeth Mitchell stuff in "Alternative & Punk," which is true, but I think you get my point). Frankly, if I were more assiduous about transferring my kids' music to iTunes, I'd probably have more songs here, but I'm happy with that list. Save for a couple tracks (e.g., Ben Folds on "Red Is Blue"), they're totally upbeat and put a grin on my face. Which, when you're cruising on that fifth or sixth mile, is a nice bump. The list is after the jump. And feel free to suggest any other workout-friendly kids music tracks in the comments.
