Unable to drag any music into my phone play lists

Question

I have just sync'd my phone and all the music in my play lists have been erased. I can still see them as purchases but I'm unable to drag any of them back into play lists to recreate them. I get the circle with a line through it when I attempt to. Any ideas its driving me potty.. the only things that have changed are updating the itunes software as promted. I have used a PC elsewhere since but have made sure that its authourised etc and all seems fine. Any help greatly appreciated??

Answer 1

Did you try clicking on the check mark (to remove the check mark) and then dragging the CD content to your Shuffle? I kept having problems dragging the CD to the Shuffle. Then I Unchecked a track and dragged over. Voila!
If you click on all the check marks on the CD, then highlight the first track, then while holding "shift" click on the last track - and drag it over to the Shuffle - you won't have to go back and forth dragging tracts to the Shuffle.
Now, I realize that I may have been the last person in the world to figure this out - but I was so excited when I did, and it makes life so e-z!
