Is the solicited node multicast address tied to the MAC address?
No, the solicited node multicast address is not tied to the MAC address. For every IPv6 unicast and anycast address assigned to an interface there will be a solicited node multicast address with the least-significant 24 bits of the IPv6 Unicast/anycast address embedded in it. The solicited node multicast address is also used for duplicate IP address detection. If you would use the all-nodes multicast address it would behave like a broadcast and you would get a reply from every node on the link.
