music again

Question

from what i understood about the music thing- as long as the music is productive and has a purpose- its OK. since music affects people very strongly subconsciously, listening to Jewish music is always productive, b/c it is influencing hte listener b'derech Hashem- w/that in mind, is it ok tp listen to Jewish music at all times? thank you CHAG KASHER V'SAMEACH ao
