Major !
On cruddy drive to work, some sadus, manowar, hellwitch, tankard, puts a spell on me and relaxes me.
Long worse drive home in bumper to bumper. Years ago when we lived in south chiraq burbs, I would work in Zion, or Belvedere, far north almost to Wisconsin,.....the drive home many times took about 4 hours, or just under or over 4 hours, depending on the idiots driving slow, and slowing down to 15mph to stare at a tow truck, or a state trooper with his lights on,
Me, for the most part I stayed cool and kept it, with help from BATHORY, rotting christ, nevermore, fates warning, malevolent creation, overkill, and many more. This is MY music, it makes me catch my breath, take a deep one, exhale and relax for the drive.
So yes, music has hypnotically and magically relaxed me during many bad years, and good years, and some very bad years in my life. I look to it for help and to unwind.
