How to counteract materialistic music
Especially in populated areas, the media constantly bombards our senses. This affects our consciousness, often in unhelpful ways. The best counteractive measure is to always chant Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. This can be sung in unlimited melodies. It's often possible to chant Hare Krishna along with radio, cinema, and TV tunes.
Some devotees, such as Yama Niyama dasa Brahmacari, compose their own Krishna conscious lyrics to popular songs. You may also think about how even many of the most mundane sounds are indirectly glorifying Krishna. "Love songs," for example, are inspired by the longing of the soul for union with the Supreme Person, but in the material world such sentiments are improperly directed toward temporary, material objects of worship.
The more we saturate our consciousness with Krishna, whether by chanting His names, hearing about Him by reading Bhagavad-gita or Srimad-Bhagavatam, or even taking audiobooks about Krishna with us wherever we go, the ever-present materialistic sound vibrations of this world won't affect us as much as if we weren't so protected.
