Buildings Selling Music

How do i make it so that i building can sell music. You click on the building and then it comes up with a list of different songs that you can choose from.

Not to be rude, but have you even tried doing this before coming here?

make a null item(s) and let the shop sell them. In triggers, make it so that the unit that aquires a spicifec song item will have it removed from the invitory and have the game play a song from the sound editor using triggers.

Okay... sounds good thnx

You could also use dialoug buttons....

In fact items are better than dialogs in this case
