Could you please provide more context or clarify what you mean by "MLPS in music CDs"?
For example, is it possible you meant:
* MLP (Mastered for Loudness)?: This is a mastering technique that aims to make audio louder, but it can sometimes result in a loss of dynamic range.
* LP (Long Play)?: This refers to vinyl records, not CDs.
* MLPs (Music Licensing Partners)?: This refers to a company involved in music licensing, not a feature of CDs.
Please provide more information so I can understand your question better and offer a helpful response.
