I will add that the scrollbar thumbs are next to invisible as well. I like that they hide when not in use, but its tedious to have to search for them when you need them. Clarification--keep hiding them when not in use, but, change their graphic to use system or higher contrast coloring when shown.
If there are no issues with files, then check the files with the tagreader utility witch comes with taglib.
If the files are read with tagreader. A full collection rescan should solve it if the files are valid and can be read.
Start strawberry from the a terminal window, do a full rescan and check for errors.
If you are using taglib older than 1.12 you should upgrade taglib. Some distros still use TagLib 1.11.1 which is an 7 years old release, so file a bug report to your distro in that case.

This would work on Linux, on Windows, you might need to find an alternative to wget.
Open the console, navigate to your music directory and launch a python http server with: python -m http.server 8123 (You need to have python installed, obviously)
Warning: this is not secure, any one on your local network can access this server, so be sure to close it afterwards.
When that is running, in a new Terminal window download the hosted page, but only the html files with: wget -r --accept "*.html" "http://localhost:8123/"
This gives you your music folder structure as html files. You could copy the folder to your phone, laptop, or whatever and browse your collection, by opening the index.html in a webbrowser. Alternatively, you could host it on a webserver, if you have one.
This is just what I spontaneously came up with, if I needed a solution in a pinch. But I am sure there are better ways.

Right click on the song in the collection tab and select "Copy to device".
The directory with the songs need to be added to the collection for it to appear there.
I tried to copy the AAC file to my iPod classic, the copy looks successful the songs can see in my iPod directory via Strawberry but there is nothing when I checked the songs in my iPod, So what I might be did wrong? please advise. Thank you.
