The spam filter learns. So each time you add something as junk, it will learn more. Initially you may need to add quite a few items as junk before it becomes more effective. Under LW's menu, Tools>Options>Filters>Junk you can adjust how strong to apply it. Adjust the slider to the right to make it stronger. I found the usual autospam such as the ipod & mp3 spam the easiest to filter out.
When you set the filter to not show spam results, I'm not sure why it sometimes continues to do so. Perhaps it's still in the learning process.
I complained about this in the beta section but there was no response & now the new version has been released.
As far as your search terms go, that's certainly not how I'd search to find an album. I don't see many titles with the word cd within it. If you want to downld albums why not consider albumwrap or search terms like title - album, or title - complete, etc. or just the title of the album or artist - title.
BTW if you're using LW, you don't need 2 firewalls. Do this test:
Bug Report instructions & sample image Is the result True/False? If true then that's fine.
