Let us suppose you have an interest in interfering with a neighboring
apartment's sound system.  So when it's the FM, it's easy to hook an old
Heathkit vacuum tube signal generator to an old car antenna and capture 
the receiver on that frequency (altho' more power on the 10.7 MHz IF would 
alleviate tuning the generator).

But what about when it's a CD, tape, or album?  Which would be better
(easier, cheaper, more effective): inducing transients on the power line 
or radiating AF hash into space?  

Transients on the power line have to get thru the power supply filtering. 
Anyway, that runs the risk of damaging equipment, which is not the 
objective.

Radiating AF hash seems like it may be better, but what is a good way to 
generate it? Would an old auto ignition coil hooked to a non-resistive 
spark 
plug and suitably triggered work well?  Or is there an easier way?

Technical responses only, please.
