You answered your own question.

The user watches the samples to download an illegal copy of that sample in full. so yes what u will be doing will be considered illegal.

About hosting, if it were legal samples released by the artists themselves it wudn't be a prob hosting them, but ur taking ur own samples (without the permission of the artist) from an illegal source, so again ur breaching copyright laws.
