Playlist Seed:  please click a point  
Sequencial Coherence (alpha = 1.0):  large steps  small steps  
Popularity Bias (beta = 1.0):  obscure  popular  
Diversity (gamma = 0.2):  drift away from seed  stay close to seed  
Number of Songs (10):  fewer  more  
Playlist Construction (deterministic):  max probability  stochastic  
\Pr(p^{[i]}p^{[i1]},p^{[0]}) = \frac{e^{\alpha \Delta(p^{[i]},~p^{[i1]})^2 + \beta b_i  \gamma \Delta(p^{[i]},~p^{[0]})^2}}{Z(p^{[i1]},~p^{[0]},~\alpha,~\beta,~\gamma)}
