''<small>WUJC being the first part of the catalog number</small>''<BR>
Discs released directly from [[Wind-Up Records]] to United States radio stations. These discs are VERY rare and are often near impossible to find. They span the band's complete commercial career from [[Bring Me To Life]] to [[Good Enough]]. These discs often include alternate Single artwork and are always in full-sized Jewel cases (as opposed to a standard J-card single case). Earlier singles such as Bring Me To Life and My Immortal are especially rare, but more recently, the [[Good Enough]] WUJC single is known to be quite elusive.
Nobody is really known to have every WUJC single, but some are close. There are, in all, twelve: 2 for BMTL, 1 for GU, 3 for MI and one for EF, CMWYS, Lithium, SS, and 2 for GE.
