I personally find unexpected and unwanted music jarring and distracting, and it has sent me away as quickly as possible when it has happened. I find it very difficult to concentrate on what I am trying to read in the description. I like to have some peace and quiet sometimes, which is difficult enough to achieve here in my house with my husband blasting the TV and CDs at full volume day and night, so I wouldn't stay around long enough to see it you were selling anything I might want.
You can, of course, do whatever you want. It's your listing.
