I've found out that I have pretty many files with broken header (shown length/bitrate was inaccurate).
Fix mp3 header does its job well... but only for a single file at time. Thats a lot of clicking for mp3 collection...

Is there a way to automate this? After 100th click I feel like a monkey

Same request.

And once again: this could be some generic plugin that executes any right-click command but applies it for each track separately or for each album separately (with definable pattern that is used to split selection into albums).

Some time ago I tried to write such plugin but the code I wrote was crashing foobar so badly that (with lack of time to debug it) I removed it all But if anyone wants to pick up the idea - be my guest

I'd love that, too. Actually, I quite need it as I tend to find a whole bunch of wrong headers every day..

you could bind "[context / playlist] Fix MP3 header..." to a hotkey for starters

(not a real solution, just fighting the symptoms, I know..)
