Music or ambient sounds for meditation?
If one is using music in order to be able to e.g. concentrate better, then it might not be the best solution. In time it could become a "crutch". 

There are many views and discussions about this and ultimately it comes down to personal preference. For some meditators it might be okay to use a crutch in the beginning, which they can later do away with.

For others, they might prefer to learn meditation or to meditate in silence. Their is no definitive answer to this.
