- Find something you like on iTunes, Spotify, whatever.

- Use the ‘start a radio station based on this song’ feature.

- When that plays something you also like, add it to your library. Keep playing it.

- If it’s a single track on an album, just add the album. The wonderful thing about modern streaming services is that you can speculatively add stuff and, if you don’t like it, just remove it. It doesn’t cost you anything! (That’s amazing, by the way.)

- iTunes learns. Keep doing this.

- By now, the Friday morning ‘for you’ playlist also has good stuff. Give that a chance. ‘Love’ the stuff you love. Add the albums with tracks you liked. iTunes keeps learning.

That’s all, really. Just listen to stuff and let the bots figure out what else you might like.

Edit: also find friends or co-workers with similar tastes. Share stuff with them. I get a lot of gold from my mate up in Cairns, just whenever we hear things we send each other the link.
