It might raise some eyebrows, but I don't believe it is wrong.

[A Google Books search for "Some listenings"][1] yields plenty of results.

By analogy, *a viewing* (of a house, or a movie) is countable.

> There will be a viewing of my new movie on Thursday.

> There will be a listening of our new record on Thursday.

Unusual, but not wrong.
