From my non-lawyer reading, it seems the prime protection in section 230 is clause (c)(1):
(1)Treatment of publisher or speaker
No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.
From section (f)(2) it would seem that youtube and spotify are interactive computer services. If say spotify provides me with a file containing music, and I use youtube or bittorrent to distribute it am I not considered publisher or speaker of the result, therefore am not liable for copyright infringement? It would also seem that I avoid the obligations that are put on the providers of these systems, as the obligations section only specifies provider not user, unlike this section.
