CDs every time please. Better quality than MP3, but more importantly it gives the presenter something to read to find out more info about you.

Always mark up the CD with your name etc - you'd be surprised how many unlabelled CDs are received in our studio.

Make sure the sleeve notes contain details of where we can find out more info about you - eg your website. The presenters will often look this up while a track is playing, to allow them to say a little about you afterwards - dates and venues for future gigs etc.

Highlight your "best" or "favourite" tracks. Yes, we know they're all good, but some of our presenters may not be familiar with your
work. Give them a clue as to which ones to play! If you were releasing a "single", which one would it be? And include any MCPS, PPL
or PRS copyright information.
