And even if I select the Recently Imported preset smartlist, I get blank although I've ripped and imported hundreds of tracks this week into where my music folder is.
The "Recently Imported" Playlist clears when you shut down MC. This is an option that you can turn off though... Go to:
Tools --> Options --> General --> Advanced. Uncheck "Clear 'Recently Imported' playlist on exit".
I agree that it would be very helpful if someone wrote a "primer" on the Search capabilities of MC. I'm a fairly advanced user of MC, but I
know there are functions I could use in View Schemes and Smartlists that I'm not aware exist because there is no easy, unified place to look for documentation (and this is proven again and again on the "how can I make this Smartlist" threads that pop up here from time to time). Unfortunately, I don't know the Search mechanism quite well enough to write the primer myself...
Also, I think the search string min221bbs gave isn't quite what you want because [Genre]="electro" won't match "electronic" or "electro jazz" but only "electro" (if I understand it correctly). I'm pretty sure there is a way to do "contains" instead of "equals" but I don't know how...
And that's why a primer would help.
There is
this thread from the amazing StiX, but that goes way over most user's heads, and certainly isn't exhaustive. There is also
this page in the Developer's Zone (though actually there isn't a way to get to that page from the Dev Zone "home" page, you have to know the link), but again, that's pretty high-end stuff. I think it would be helpful to have a primer that includes the high end stuff, but only after explaining the more "normal" search options in a clear and easy-to-understand way. Using the existing documents and jumping right into database expressions is a bit like trying to learn PERL by looking at example code with no explanations ... Not real likely for us mere mortals.
