Hi Jock,
the B2 uses an external database , Musicbrainz,, to get the details of a CD.
Sometimes you get mismatches or multiple matches and even no match.
When you are ripping are you using the B2 front panel or the web UI ?
If the front panel then turn the rotary knob to scroll through the choices and select, you should always get a choice of Album nnnn , e.g. Album 1234
If using the Web UI then in the bottom left it should tell you how many choices. Click on the down arrow to see what they are.
