Thanks for your reply.
The only way to do this is by manually creating a playlist? I have hundreds of albums on my device so that would take a long time.
In case I didn't explain very well:
My file structure is as follows:
Artist 1 > Album 1, Album 2, Album 3
Artist 2 > Album 1, Album 2, Album 3
etc
Using file browser, if I 'Play All' it shows all artists songs but places all thtracks in alphabetical order instead od adhering to the file structure. Also, this prevents me from playing songs both on the player and SD card at the same time. Same thing happens with database, except I think that shows all tracks from both sources.
What I want to do used to be easy prior to installing Rockbox, nothing else has changed yet functionality has suffered.
