It should use ^Title and ^Artist, otherwise something with "Artist" or "Title" will give wonky results. More importantly, you can get the same results by just one or two dbus-send commands instead of using that "sp" script + something to clean it up. The sp-metadata function uses tons of processes to clean the output[1], and sp-current launches a few more. If you're doing this in a loop for your WM status display this sort of stuff really adds up. Even on modern systems launching processes isn't free and relatively slow, and launching >20 of them every few seconds is going to use non-trivial amounts of CPU and will needlessly drain your battery. I don't really know what that dbus command outputs, but I bet that with you might go a long way with "dbus-send ... | grep -o ..." or something. So in general I'd say this is a classic case of "you're not even using the right solution, and no amount of GPT is going to help".
