Don't alter the timestamps on the files
Bliss alters the timestamp on each file it fixes, this is really unwelcome behaviour. The timestamp is an important part of the metadata and I don't want it altered. I know that it is possible to change the file without altering the timestamp (on NTFS at least), could this feature be added?
Yep, I can definitely see the use case, being a LMS user myself and relying on "New Music" too... it does annoy me as well.
Squeezebox uses the modtime to work out which is your 'newest music'. It also helps me mentally locate related music in the continuum of my memory!
Hence, I strongly agree: bliss needs to have an option like flac's --preserve-modtime.
When I reordered my old CD collection alphabetically instead of in order of acquisition (when I got married - :-) I lost this important mental connection. I miss it. I got it back with Squeezebox.
And actually I'm sometimes tempted not to use Bliss (good though it otherwise is) because of this problem. For some reason, every now and then it chooses to replace artwork and old stuff pops into my New Music section. Very undesirable.
Preservation of modification timestamps is a feature in many tools that alter media libraries, sets of files (e.g. renaming), and so on. To me, this is a deal-breaker/showstopper.
