Currently the only filters for search in iTunes are by song, album, artist and composer. Is there a way to search by genre in iTunes?
In the current version of iTunes, it works when you uncheck "Search entire iTunes library" in the search bar. (To get there you click the spotlight-type icon in the iTunes search bar.) I had the same problem, and that worked for me!
Seems like you cannot search by genre in iTunes, however you can perform a search request like this in Spotlight:
kind:music genre:jazz which will reveal all for tracks that have genre set to jazz in their tags.
Assuming you are using iTunes 11 then there is a bar under the window that shows what is currently playing and one of the buttons should say Genre and will usually be 4th from the left. If you click on that then it should sort your library by genre. Hope this helps!
On the left hand side: select songs to show the grid view. Add columns if needed. Go to View in the menu bar, select column browser.
I got this to work in iTunes 22.214.171.124: If I have Genre visible as a column, then I can search for a genre in the search box, and it limits the visible songs to those that are in that genre. But I have to make the Genre column visible first; searching by genre doesn't work otherwise.
