You could try to use Go>smb://sharedfolder/music$ from the Finder.
If your network has a domain controller, or if the workgroup name is not the default "Workgroup", you may want to use "/Applications/Utilities/Directory Access" to edit the SMB/CIFS configuration. Ask your network admin for the Workgroup/Domain name, and for the LAN IP address of the WINS server. Select SMB/CIFS from the Services tab in Directory Access, click on Configure, and enter the information your admin gives you.
Click on OK, and hopefully you will be able to access the smb share.
