They are documented in the Compendium, an in-app purchase.
Moneykeeper's Melody, as the name implies, helps you keep your money away from bandits. It's slightly useful around Savage Crossing.
Ballad of Reason is essentially the spell Disbelieve. It's useful against sorcerers, such as the Ancient Heroes in Horon's Sanctum.
The most useful song early in the game is Song of Life, which is free healing. Later you will be using Spirit Chant, which slowly restores Spell Points, a lot, especially after magical damage areas that also suck away Spell Points (e.g. in the Tarasz Passage). IMHO. Spirit Chant alone is worth having a Bard in the party!
For most of the game, your Bard will want to have a Bardsword, which lets him sing unlimited songs (as far as I have seen) without wine or beer. At some point, though, you'll want to switch him to a Singing Sword, if you're lucky enough to find one!
