I'd prefer a general approach that used the first column as a key, and the rest as the value...into a dict/hash. Then if you need the Album title or something else later, it's easy to alter.

I'm sure awk could do that, but with Perl:

  sp current | perl -nE '/(\S+)\s+(.*)/ and $d{$1}=$2;END{say "$d{Title} by $d{Artist}"}'
