Propose exising values when editing compilations

When you have to correct artists on a "best of" made of several CDs, usually the same artists come back several times. It would be a nice feature to have the best match to be presented as you type (à la Excel). If you have already a song of Orchestral Manoeuvres in the dark, typing Or in another song should suggest the complete value.

Even better, based on other song data, make more clever proposals (real time check of the possible songs data).

See this post for a similar proposal:
is it possible to save manually entered data locally for re-use?
