Why do you believe that it's wrong to own these things? What makes the Rolling Stones "ungodly"? To me, it sounds like you have a lot of needless guilt about these things. By all means, if you do not wish to own things for your own personal reasons, that's fine obviously. But "secular" is not the same thing as "bad".
I wear secular clothes, everyone does. They're called pants, or socks, or shoes. I eat secular food, everyone does, it's called fruits, vegatables, bread, pasta, etc.
Secular isn't a bad word. But there is a strange sub-culture that treats it that way, though it doesn't really make any sense.
When Scripture condemns worldliness it isn't talking about music, clothes, food, or anything like that. It's about about the values of this present fallen age. We are called to a different way, the way of Jesus, which is about taking up our cross and following Him, and loving our neighbors. Worldiness isn't listening to rock music, worldliness is mistreating the poor, the hungry, and the weak in our midst. Worldliness isn't enjoying getting a slice of pizza for lunch, it's being rude, condescending, and holding grudges.
Godliness is not in what music we listen to, what clothes we wear, what movies we watch; it's in cultivating the fruits of the Spirit in our lives through lives of faith and faithful obedience to Jesus.
"For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another. For the whole law is fulfilled in one word: 'You shall love your neighbor as yourself.' But if you bite and devour one another, watch out that you are not consumed by one another.
But I say, walk by the Spirit, and you will not gratify the desires of the flesh. For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do. But if you are led by the Spirit, you are not under the law. Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God. But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. And those who belong to Christ Jesus have crucified the flesh with its passions and desires.
If we live by the Spirit, let us also keep in step with the Spirit. Let us not become conceited, provoking one another, envying one another." - Galatians 5:13-26
The commandment is "Love your neighbor", in which we deny the ways of the flesh (in all its arrogance, all of its wrath, all of its lusts, all of its hunger for excess, in its laxity toward what is right, etc) and instead walk in the life of the Spirit, who produces in us love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control, etc.
The ways of the world are hateful, violent, angry, dominating; but the way of Christ is to lay down one's life for others in love. Which, of ourselves, is impossible because of sin; but by the power of the Spirit who is ours in Jesus Christ our Lord, we are the workmanship of God and He is continuing the work He began, and will complete and make perfect on the Day when Christ returns and God makes all things new.
So the most important question is this: What do you think you will gain in giving away all these things? If you believe that in doing so you will be more holy, or walking toward holiness; then it is essential to let you know that this won't do that.
If you so desire, out of conscience, sell these things to those who would like them (for there is nothing inherently wrong with them), and then use the money for something good and godly, like give the money to a charity, or even to a random homeless person you see.
But if your chief concern is that that God condemns you for owning Rolling Stones records, then you can relax. What God is concerned with is what He has revealed and told you in His word:
"He has told you, O man, what is good; and what does the Lord require of you but to do justice, and to love kindness, and to walk humbly with your God?" - Micah 6:8
