Does this default mean that it will work with cue sheets without me
specifying a specific md5_offset parameter ?
If not, is the offset in the database an offset in the compressed or
uncompressed audio data ? If it's an offset in the compressed audio
data, this should work.
Is the audio_size of an individual cue sheet track also available in
the database ?
I suppose I might need this if I like to ensure that I don't include
data from the previous or next track in the checksum calculation.
