The recording multisearch component used in Playlists, MBID mapping modal and manual list submission modal can be improved.

Quoting Rob:

[We should] use a different data set and search technology that is more suited for user interaction. (the data index we have now is geared toward the automated MBID mapping process). A user centric index would our new canonical recordings index with results being weighted towards album tracks, rather than all the other guff that you find getting in your way.

Previously, the ticket also contained implementing this stopgap measure:
Allow a user to past a recording MBID into the search field and add that specific track to the playlist. This should work as a stop-gap measure until we can put #1 in place.

Namely the first initial option would be to have it so that recording lookups is possible using MBID's.
