Music Solutions

I'm currently trying to divorce myself from paid streaming services so I'm looking for ideas to pursue. Those of you with huge music collections, what are your solutions for listening at home and on the go? Self-hosted streaming? Modern mp3 player with huge amounts of storage? Modified legacy MP3 player? What are the upsides and downsides? I'm really just looking for what options are out there and if there's any kind of general consensus on what's best.
