I experimented with selling music for Unity, and honestly, I don't think users are looking for music packs, generally. There are more than enough people offering free music, few Unity developers make it far enough through development to care about music, and anyone likely to actually ship something usually wants custom music anyway.

I've gotten that feeling.
If I for example compare Unity's store to Unreal's, Unreal doesn't even allow free stuff.
That doesn't mean that Unreal's users can't get free assets and music elsewhere, but maybe they are more interested in buying music?

We can install other musics from other play , 

I'm just a begginer, but personally: mixable loops. These are easy to change on the run through snapshots... also, it would be more efficient than storing a full track. 

I've bought music for games before and there are several things I look for when browsing music loops or packs in asset stores. Not only do I consider the technical quality of the pieces but also their overall value and if the theme matches my design.

When making a music pack of your own I'd suggest considering who your target audience is carefully. While professional studios can have long lists of music tracks tailored to their game, the indie developers who buy audio packs in asset stores are going to be more focused on getting the mileage out of their money. So, looped audio tracks are much more useful than just a traditional piece with a beginning, middle, and end. Also consider having the beginning and end of the tracks match for all main pieces in the pack. In addition, while music and audio are often neglected in indie development, it's often because developers are on a tight budget and/or timeline and that's where they can get away with spending less money and effort. To increase the value of your pack you might also add sound effects for UI, combat, environment, ambient, and misc applications. Also, consider what type of game it would be for and tailor it to fit a unified theme. Soft piano in a background melody might be good for some strategy or turn-based designs but not really for games all about or featuring intense action scenes. Basically, create themed packs with as much extra utility as possible.
