ITunes Accounts

Over the last 8 years I have ended up with two iTunes accounts. Does anyone know IF is possible to transfer everything into one account? If yes, how?

To my knowledge you cannot merge Apple IDs but you can import the contents of one iTunes library to whichever you would like to call your main iTunes library. iTunes will pick up the track information in the media files but it won't pick up the ratings,play counts etc.however.
Before you transfer your music go into the Advanced prefs in your main iTunes account and check 'Copy files to iTunes media folder when adding to library'

Thanks Pendlewitch. I really appreciate your response. I will give this a try.
