With meditation I myself need quiet to begin with. I personally cannot abide meditation music, but I do know others living in a noisy environment will use it in order to block out annoying sounds. Many of these can be found on youtube, even spotify for free.
I personally do most of my meditative work in the morning, I get up earlier than everyone else anyway, so it works out for me. I am by no means saying miss out on sleep, but if you can go to bed earlier and get up earlier, you may find it easier.
As for a beginning meditative practice, watching the breath is the most basic, yet one of the most effective techniques of accomplishing many aspects of meditation. It is the practice which will always be in my own routine as a firm foundation.
Simply sit in a position you can hold for a period of time, to begin with say 15 minutes, preferably with a straight back, and simply focus your attention on the breath and mentally repeat "The breath moves in, the breath moves out". If other thoughts come into your mind, simply allow them to come and go and draw the attention back to the breath. Don't fight the thoughts, simply pay no attention to them at all.
Once you have done this for a few weeks I would imagine you will know about the contents of your mind, how it works, what needs controlling and other aspects of your being. You may also begin to sense the internal energies within you- which to me is the next step.
Simply having endurance, deterimination, and being open and receptive will aid you greatly.
Whilst meditating read all that you can about magic, there are many pdfs which can be found online. If the books signify basics or state that a practice should be upheld for a certain amount of time, listen. Do not run before you can walk.
Some Books I personally recommend-
Modern Magick by Donald Michael Kraig.
12 Steps to Spiritual Enlightenment by Dr Israel Regardie.
Spells and How They Work by Janet and Stuart Farrar.
Raja Yoga by Swami Vivekananda.
There are countless others. If it is more witchcraft you are interested in I would start with the Farrar book. Ritual magick is Regardie and Kraig, however, Kraig also touches upon more witchcraft type practices as well. I personally think Kraig's book is one of the best out there. Regardie's is short and sweet and is designed to be practiced over the course of a year.
