Hallo,
I'm using MusicBee since the future of WinAmp is not clear.
What I found is, that MusicBee seems to search in the tags of music files, but not in the file names.
It does not find files without tags where the file names do contain the search string.
For example, a file with with the name "Bodycount_Hey Joe.mp3" is not found if searching for "Body".
If this could be added to the search it would be fine!
