i do not watch anything more than once.
many times, if i am "watching" a movie, i will fast forward to the final scene to see how it all turned out.
when i watch a movie (rarely), i get impatient because the early scenes are just building blocks that set the scenario that will be finalized at the end of the movie.
mostly, i get so impatient to see how it all turns out, that i fast forward to the end to see what the finale is, and i consider that i have saved time in doing so.
i am not interested much in movies.
with music, i get the idea early in the song, and i most often stop the playback and try to play it on my synthesizer because i want to be personally involved.
there is some music that i will listen to entirely because it is genius like frank zappa or mozart. i can not recreate that so i sit and listen.
