So I'm streaming the great Dillinger Four record Versus God and I notice that Rhapsody wants to suggest some tunes. OK. I scroll down. Huh? "Seal Uncut", Seal; "Rocket To Russia, Ramones (Check. Got it already. In my heart. Forever.); "Number Ones", Michael Jackson. Huh? I never even bought "Thriller"! And to top off the absurdist disconnect, "Jupiter's Darling" by Heart and "Maximum Backstreet Boys" by guess who. WTF? And when I look back it has changed. Now it's recommending "One Track Mind" by Eric Clapton.
The last stuff I streamed off of Rhapsody was: Opeth, a black metal band; Drive-By Truckers, country guitar apocalypse; and Morrissey's cover of "Moon River".
Rhapsody, your heuristics need serious attention.
