Hi there I am having issues with Media Rage. I use the app to populate the ID3 tags with information from the file names of the MP3 files. I have no knowledge of regular expressions or anything like that - but I tried none the less to edit to do what I wanted but I couldn't get it to do what I wanted. I will explain my problem and hopefully you can provide me with the correct expression to use in your program to do what I want. My MP3 albums are named like this tracknum__artist__album__track All the filenames have underscores instead of spaces. So a typical track would look like 03__the_zutons__tired_of_hanging_around__why_dont_you_come_on_over_valerie Now the expression built into the program which is 00-Artist-Album-Title works - I just changed the dashes for double underscores. Some of my albums though have remixes on them. So there is a further __ to seperate the mix name from the title of the track. Eg 03__the_zutons__tired_of_hanging_around__why_dont_you_come_on_over_valerie__super_good_remix When using the expression for the 00-Artist-Album-Title filename won't work. It puts the data in the wrong files. After a bit of messing round I did manage to make an expression that would bind the last two instances together but it causes filenames without the last __ instance to fail. Do you know what string I would need to use so that it will work with both? Many thanks.
