The rules are:
1 The wizard must choose an album. Then, every track on it is a spell. Whenever the character learns that spell, the GM describes it's effects, using the song title (if this cannot be possible, use the song theme or feeling).
2 The wizard earns a spell per level, following the strict album's order.
3 The wizard can only know 4 max spells (like in the pokemon games). When he/she tries to learn a fifth, another spell may be forgotten; or the new spell withers away and is crossed from the list (this is for preventing players from abusing the system by picking a Rancid or Bull of Heaven album)
I'll make an example there using a classic: Pink Floyd's Wish you were here. (Note: the descriptions are system agnostic. I can not help tending more into the narrative style)
1 - Shine on you, Crazy Diamond: Anyone touched by the wizard emits a subtle, white glow; while his/her feet subtly detach from the ground; as gravity no longer pulls him/her down. Swimming in the air is possible as there is friction. Requires ongoing concentration by the wizard.
2 - Welcome to the Machine: The arcane technomancer wizards can bind the soul of a recently dead person into an engineered golem. It can be made of any kind of material; but the whole construct must share a key trait with the hostage personality or previous body.
3 - Have a Cigar: This spell can lit anyone in flames as long as the wizard is shaking hands with him. This picture (album's cover) illustrates it nicely:
4 - Wish you were here: By drawing a circle and praying, the wizard may attempt to summon a soulmate; always granted that he/she/it is willing to help. Dead people may also come; as ghosts or spectres.
5 - Shine on you, crazy diamond (Part II): This spell can make anybody affected by the spell #1 to burst in flames spontaneously, by a snap of the wizard's fingers.
