Hello, I recently added some songs to iTunes, but they don't appear in the Library. The appear only under the playlist "Recently added". I added the whole folder to the iTunes library (drag and drop). I tried searching for the artist in the library using the search bar, but nothing happened. I used a third party program to change the audio format of the songs to see if this was the problem, but it wasn't. Anyone knows how to fix it? I can play the songs, but going to the playlist I just mentioned. I have OS X Lion and iTunes 10.6.1. I rebooted my macbook pro 2 times and the problem is still happening. Please help! The songs are in mp3 format and I tried changing them to m4a and AAC. Nothing happened!
