Can you please help? I want to do a mop-up, having fixed a ton of tags in my library. I'm filtering on before I started batch-fixing tags on the tenth, so I'm starting my filter with: "%\_file\_mod\_datetime\_raw%" LESS 1688943600 AND What I want for the second half of my filter is the ability to break these down into batches. I figure the best way to do this is by albumartist's first letter, so I want something like: "%\_file\_mod\_datetime\_raw%" LESS 1688943600 AND albumartist STARTSWITH "A" What would be the correct syntax to achieve this? Thanks in advance 🙂 ---
