The listing for Future Disco: Poolside Sounds Vol. 13 includes a 1:07:37 continuous mix at 116 BPM in B-flat major and, from there, an individual selection that makes the compilation's architecture easier to read in detail. All material is on Future Disco and alternates Deep House with Nu Disco / Disco. The fastest stretch begins with Huxley and Londen Summers' It's You at 129 BPM in B major, followed by Lewis Taylor's Vision of Love at 128 in D major.
The first area maintains a 126-to-129 BPM band. All About Us, Huxley's vocal mix for Thorsten Hammer and Leroy Barry, and Kideko's Burning Love share 127 BPM and B-flat minor, while belonging to Deep House and Nu Disco / Disco respectively. Davide Dev's What You Need reaches 128 BPM in G-flat minor; Tiger Stripes' Say Yeah sits at 127 in E major, and Ben Reggie's Here We Go at 126 in F major. The labels cross within a very close speed margin.
After that, the tempo falls in stages rather than a straight line. The Bamboos and Cosmo's Midnight's I Don't Wanna Stop appears at 124 BPM in F major, creating a data link with Here We Go. Sem and Gourmet Groove's Ecstasy is listed at 125 BPM in D minor. Later, NATE08 and Benni Ola's Waiting returns to B-flat minor at 125 BPM, while Alma Negra's Where Is The Love repeats G-flat minor at 123 BPM, a key already used by What You Need.
The closing stretch places the selection between 120 and 115 BPM. Tempest and Benni Ola's Surrender to the Night is listed at 120 BPM in E-flat minor; Rona Ray and NATE08's Addicted at 115 in E-flat major; Louis Baker's Larse remix of Keep On at 118 in G minor; and Ekkah's Lifetime closes at 115 in D minor. The individual 115-to-129 BPM range and recurring keys provide a concrete map for relating cuts through tempo or key proximity, without reducing the compilation to either one of its two categories.
