Given that a lot of datatags that are imported is inconsistent, contains double space, inconsistent with capitalization, artist names written different, track numbers in title, artist name in title, etc.
Given that from different sources a collection grows with similar tracks.
And some more of those time consuming manual maintenance issues...
Would it be nice if some feature is embedded (or external) that helps cleaning up the data and making live easier by selecting 'best' tracks for duplicates.
In multilingual it might be difficult, some more generic might work, like left space, double space, per word capital..
And for duplicates some logic to determine matches based on title and artist despite different codecs and varying length.
Let alone selecting priority for 'best track' based on quality and disk\folder location.
based on experience : this will be more complex than adding a keyboard/MIDI shortcut....
