Hi Lewis,
it seems your album(s) are not finding a correct match in the database that the Brennan searches.
If you have a PC or Apple device with a CD drive you could rip the CD there and then upload to the Brennan.
Some of the available ripping software can find a correct match when the Brennan can't.
I personally always rip on my PC before uploading because I have more control over track naming.
If this is an option for you then one of us on here can give further advice if you need it.
John
