WAVS are difficult because they support metadata in two different formats, and we try to support both although we prefer ID3 chunk. Jaikoz should read ID3 and INFO metadata, currently only reads ID3 this can cause problem.
i.e ID3 has no artist field, but INFO does.
No artist is displayed and if nothing entered even though we sync tags the INFO is left untouched so left with situation that Jaikoz says no artist tag, but other applications may display one. Better to default to ID3 but use INFO data as well when ID3 data missing
