Hi Dave,
The B2 currently does not display the track artist in the UI only the album artist, which for a compilation would be "Various Artists" or similar.
I get round this by using 3rd party software to rip my CDs on my PC and uploading the tracks to the B2.
I use Exact Audio Copy (EAC) for this. (other software is available !)
EAC allows you to customise the file name of the track so I include the track artist in the name of the file so that is displays when I play it on the B2.
e.g. 02 Handbags and Gladrags [Stereophonics].flac
EAC does create a metadata tag for the artist on each track of an album so it is there if future B2 software versions are able to retrieve the tag info and display it.
The screenshot attached may help with what I describe.
