Only Reb. Kanievsky Z”L was Reb. Kanievsky. You have to be the best YOU and no one else. Learn from the middos of people whom you admire, but retain your own spirit and personality. Nothing that happens instantaneously tends to last. Every new middah that you accept on yourself is precious, and you don’t need to do it all at once. Make certain things a part of your world slowly, and bit by bit they will be permanent aspects of your observance.
I am not telling you to listen to or NOT listen to the type of music you like. I am advising you that there is always room for growth in all of us, and what you are not ready for today, may be something that you will eagerly incorporate into your hashkafa tomorrow. Do the best you can and make your observance NOW count, even if you are listening to music that some people feel is wrong for you. Many people feel it is wrong to listen to ANY secular music of any type, even classical music. Does that make all of us who do listen to it, NOT frum??????
