How to delete songs from playlist in Itunes

Using a PC, not a mac.

Downloaded Itunes. May have clicked on Live update. Whatever I did, my Itunes library was loaded with 60 tunes which I do not want. Tried to delete them, but Delete under Edit is grey.
Selected a tune to delete, hit delete on my keyboard and nothing happened.
Hit control+delete and nothing happened. Went to Edit, but Delete is grey.

Read somewhere that maybe I cannot delete if I have selected live update. Cannot find out how to opt out of live update.

What can I do to opt out of live update and delete unwanted tunes from playlist?

Finally, I deleted Itunes, Quicktime, and most importantly, located all of the tunes which were stored elsewhere in my computer, and re-loaded in Itunes. The removals and reloading worked.

Thanks for posting your fix!

Well, something good happened for/to you this past Friday, August 28 because it was my birthday. Turned 27 finally. Ah shucks, can't tell a lie; I passed that number long years ago. Miami was old stomping grounds some years ago. Well, Hollywood is/was more correct.
