Obviously not as mature as Spotify (yet), Youtube Music still offers a way in to listen to new music and save playlists online etc:
https://music.youtube.com
The website is fairly demanding but can be reached with Leopard Webkit and TenFourFox - better still use Fluid (relinked to Webkit) or a FoxBox - either way make sure you have the most up to date user agent in place or it won't work.
I've been trying it on my 1.25Ghz MDD and DLSD - on opening it pushes 100% CPU but once you select your music it settles to around 40% - obviously multiprocessor Macs/G5s will fair better
