Hi,

The artist-recording label similarity attribute can be used (with suitable
weights assigned). However, isn't it possible that taking this similarity
via users might not result in accurate results, as people who like one
artist belonging to a recording label, might not necessarily like other
artists under the same recording label?

By the way, this is the proposal I've submitted -

Information about the Indian Movie Recommender System (my Final Year Project
which uses CF algorithm) is put up here -
