“…Intrusive songs may also involve a sense of reexperiencing. When people intentionally imagine music, for example, they reexperience many aspects of the music: the song replays over time (Halpern, 1988a;Halpern, 1988b), involves various aspects of the musical experience (Bailes, 2007), includes pitch information (Levitin, 1994), evokes emotion (Lucas, Schubert, & Halpern, 2010), and involves the same brain areas as listening to music (Halpern & Zatorre, 1999;Halpern, Zatorre, Bouffard, & Johnson, 2004;Zatorre, Halpern, Perry, Meyer, & Evans, 1996). The third area of similarity is that intrusive songs appear to include a repetitive quality such that they return frequently to awareness much like some instances of involuntary memories (Berntsen, 1996(Berntsen, , 2001) and intrusive memories (Brewin et al, 1996).…”
