Spooky ambient music for role-playing is not exactly a crowded field, though many DriveThruRPG customers will already be familiar with the music of Nox Arcana and Midnight Syndicate. Erika Lieberman's "Vampire Castle" is a good addition to this genre. Some of the features that make this track good music, however, limit its use at the role-playing table. For example, thunder rolls in the background at several points in this track; DMs will find it awkward, then, to use this track behind a role-playing scene with a clear night. The music is good, and haunting, and fits the theme perfectly, but it has more limited applicability than other offerings in the same genre.
My biggest complaint about this track is technical: the track needs better ID3 tagging, and some album artwork. This complaint also applies to Erika Lieberman's other three tracks released at the same time: "Forest Journey," "Desert Battle," and "Prosperous Tavern." See my individual reviews of those pieces for comments on their content. Sonic Legends needs to create a virtual, ever-expanding "album" for these tracks, and needs to provide appropriate ID3 tags. Of the four, only "Vampire Castle" came into my iTunes with the track name preserved as such, and with "Erika Lieberman" listed as the artist; all others ended up with the file name (complete with underscores) as the track name, with all other ID3 tags empty.
I also have one other reservation: this track is expensive compared to other MP3 products sold at DriveThruRPG and elsewhere. With comparable products running as low as $0.50, and with the iTunes Store and Amazon downloads conditioning customers to expect tracks that cost $0.99 or less apiece, you have to think twice before buying an MP3, even one as excellent as this, for $2.99. Lieberman's other tracks have more to commend him in this regard; for the same expenditure (plus one penny), you could get three tracks from Nox Arcana's Transylvania album instead. With stiff competition at a lower price, this particular track is a hard sell at $2.99.
