What I get from this is...If you "hear" something that's helpful or beneficial to you, then it's probably God...But, if it's the opposite, it's due to your being spiritually mis-aligned?
Well, Biblically speaking, it could also be spiritual influence from satan or demons - though the Bible actually says very little about such things, and it can sometimes be a challenge to distinguish between pop culture and actual scripture (I personally can really only think of the handful of passages that address temptation from Satan. Such 'temptations' would ALSO be thoughts that are foreign to your typical thought processes, and if they DON'T reflect the character of God, then they may be from Satan instead.)
EDIT: And I didn't say that it would be something that's "helpful or beneficial" to you, but rather that it would be something that is in line with the character of God. Your statement again alludes to the misconception of non-believers that the purpose of God in one's life is to make your life into a bed of roses, which is really the exact opposite of what the Bible says. I am reminded of some verses in 1 or 2 Corinthians (I cannot remember the specifics) which essentially says that God loves us too much to be concerned with our worldly needs - that the best thing for us is often to be faced with adversity, so that we can grow from it spiritually.
