Ok Tilly lets have a go.
Open up the You Tube tab in your normal way.
Click on the "Sign In" button top right of the home page.
Click on "Create An Account" button under the log in form on the log in page.
Note....If you already have a Gmail account, you should have a YouTube account. Use your Gmail username and password to log into YouTube.
Fill in the requisite information using your usual private email address if you do not have a gmail account.
If prompted supply a phone no (I used my mobile) to supply verification that you are not a bot. You may get a text with a verification code. If you do, enter this code on the You Tube site as requested.
Once you have done this you will be able to set up your profile that includes a photo from your files, and user name that is displayed publicly on You Tube. A lot of what is there is not necessary but I use my AB nom de plume and avatar picture so as to stay anonymous and would suggest you do similar. By the way You Tube do not bombard accounts with spam and title tattle.
The main thing is, now when you play an track that you want to keep you can add it to "FAVOURITES" list to listen to any time you click favourites and you are logged in. It will even play your whole list and in random sequence if you ask it to. I have checked the keep me logged in box so that I automatically log in when I open the Tube tab. Careful what you actually add to your favourites or you end up with a load of junk. Check the sound quality before you "Add To Favourites" a good guide being the more plays it has had the better and safer the post will be. Official videos are always the best. Yo can have more than one favourite list and now post in the comments below the track being played. I will also post a link that may help.
