Why all three? I use either WAV or REX, so I can justify two-thirds of the download, but the Apple loops go straight in the bin. An Apple person might conceivably keep the AIFFs and REXes and dump the WAVs. Many users may just want one of the formats. So, why not build those option into your server? I'm sure the bandwidth at your end isn't free, and adding the various (7) combinations is a simple database operation that'll take a few minutes and save you dough, and save us time.
