Hi,
It looks like in some of your taste profiles you have a number of successfully resolved items. I also took a look at one of your tickets (the one for the catalog containing 1001 items). I see about a third of the items that failed to resolve, however the remainder did successfully resolve, which you can see by reading the catalog and looking for the artist_id and song_id. Name resolution usually fails either due to bad data (bad misspellings, bad artist/song combinations) or because we do not have that artist/song.
Again, it does look like items are resolving in your taste profile so you should be able to work with that.
