I didn’t listen to either clip and I know nothing of that composer, so you can decide if my comments apply to your sepcific situation or not.
Yes, music affects people. In the same way, art and literature and even architecture also affect people. So it’s certainly possible that the second clip you posted can disturb your peace.
That said, I do not think that an individual’s personal worldview automatically infuses everything they create with some sort of subliminal message pulling people toward that worldview. If that first clip is a beautiful, peaceful song, I don’t think it becomes occultish solely by virtue of the fact that the composer dabbles in the occult.
Just think if that were true for all worldviews: Anyone who listens to a hymn that is written by a practicing Catholic feels inexplicably and forcibly compelled to renounce sin and embrace Jesus as their Savior. Do you see that happening? I don’t. If I did, I would load my iPod with Catholic penned hymns and blast it for everyone I come into contact with. Evangelization would be a piece of cake!
I do believe there is an objective element to music. For example, lower pitch notes more easily create an atmosphere of somberness, whereas higher notes more easily convey light-heartedness. If there was no objective element, composers would not be able to craft music for movies with the express intent of eliciting emotions such as suspense, surprise, or joy.
However, we cannot discount the
subjective aspect of listening to music. People experience this sort of thing when they have a song that is “their song” with their boyfriend or girlfriend. If they go through a messy break up, suddenly that song elicits an entirely different set of emotions that has nothing to do with the objective aspects of the music. Perhaps your association of this composer to the occult is so strong that
anything he has composed (no matter what) carries those negative associations
for you. If that were the case, it may be best for you not to listen to it.
Further with regards to the objective vs. subjective aspects of music, I don’t think that all musical associations – even common ones – are necessarily universal. For many people, the double bass drum of a heavy metal song is disquieting (to say the least). For me, it’s just high energy. It’s not always easy to clearly dillineate between the objective and subjective.
