You can see your music by looking in iTunes, all the music you purchased from the iTunes Store is available from the cloud, and if you are using iTunes Match all the music in your iTunes Library whether purchased from iTunes or not is in the iTunes cloud as well.
Thank you Csound1, ok I guess I did manage to delete it but now when I copy new mp3 files they come as mpeg and iCoud won't accept them? Why? Do I have to convert them all now or can I set it somewhere to take them as mp3's. Appreciate the help. Have a great day! Cheers Steve
