If, when you move, you can't take a new friend with you, i would just stick with music. I sold a broodmare, and penned the other up so she couldn't run around too much and she paced/cried then got over it. You will delay the process if you introduce another buddy then take it away again.
If you can take it with you, then i would think about it, but I have a goat that my Mom loves ( she won't let me get rid of it and it ROAMS FREE, ewww) and she is constantly getting into my hay and feed because i can't keep her penned up. If you do get a goat, get a big one, lol. Big goat means harder for her to get under fences and if you have tight enough fences maybe it will stay in them.
Watch out for ones that have horns. Most new people will play with them, which makes them mean, and then the ones that try to escape, they can get caught in the fence and die before any one notices. Mine gets caught sometimes when i try to pen her up and i have to go fight with her to get her out, lol. Not a fun thing to do.
