Usually, when I hear one highly energetic tune, I like to segue it with a tune that's similarly upbeat. iTunes shuffle mode accomplished this yesterday, pairing two unexpected tunes in my library. Acoustic Alchemy's instrumental, "Wish You Were Near," establishes a jazzy dance vibe similar to "Shuckatoom," the "American Top 40" theme song of the late '70s and early '80s. Hearing it flow into an unusually vigorous Suzanne Vega tune, "Unbound," was refreshing--and a transition I hadn't considered.
