As the subject line says, I wish to prefix the title of a track with the last name of the composer, eg:
Composer tag contains: "Bach, Johann Sebastian"
Title: Sonata No. 1 in E-flat major BWV 525
Title should read: Bach: Sonata No. 1 in E-flat major BWV 525
Note: ALL Composer tags of my classical music tracks are populated with this configuration without exception: LastName, First and other names. Hyphenated names: Rimsky-Korsakov, Nikolai. The single comma in the name is key to identifying the Lastname the precedes it.
I am trying to learn the subtleties of regular expression, but if anyone can help me with this I would be very grateful.
