Table 3
Percentages of free‑text responses, by culture and CP user group (user ; interested non‑user ), that implicated the three purposes and two connotations of the CP Framework. Uninterested non‑users () were not asked to provide projected purpose(s) for engaging in CPs. Percentages greater than 45% are bolded.

Table 4
Ordinal responses regarding broader social connection through music. Participants (user ; interested non‑user ; uninterested non‑user ) reported their level of agreement, on a scale of 1 to 5, to the following statements: (Q2a) “Diversify my music library,” (Q2b) “Increase ways in which I discover music,” (Q2c) “Require less of my time and effort to discover music,” (Q2d) “Require less of my time and effort to manage music,” (Q2e) “Require less of my effort to enjoy music,” (Q2f) “Make listening to music more enjoyable,” (Q2g) “Change the music that I listen to,” (Q2h) “Positively influence my music taste,” (Q2i) “Make me appreciate music platforms with CPs more,” (Q2j) “Make me more open to new experiences in general.” We report overall model output, significance of individual predictors, and significance from follow‑up pairwise t‑tests ( ; ).

Participants reported their level of agreement, on a scale of 1 to 5, to the following statements: (Q3a) “In my case, personally, connecting with others through music has declined,” (Q3b) “In my case, personally, music has helped to connect with others,” (Q3c) “In general, connecting with others through music has declined,” and (Q3d) “In general, music has helped people connect with others.” We report overall model output, significance of individual predictors, and significance from follow‑up pairwise t‑tests ( ; ).
