Yes, if you surround the username in @ symbols it turns up in your notifications just like a reply message. Anyways, I'm not entirely sure why thenewgreen passed the torch to me on this one. I'm a mediocre music listener and I mostly use Spotify. For the digital music exchange I think that you should do a post where people post all their mixes using whatever service works for them. Grooveshark comes to mind. Spotify has an in browser way to listen now (I think?) and youtube. Bandcamp or Soundcloud or whereever particular artists have their music available online. The only concern I would have is that some music is restricted by location which may be a pain for the international nature of Hubski. But I'm a big believer in dealing with problems like this as they arise. It really just depends on the artist selection that individuals make. Some aren't on Youtube, some aren't on Spotify, etc.
What a great response. That's why I turned it over to you. I literally use Spotify and that's it. Thanks insom.
I would add that perhaps the very best way to find out is to just ask the person you're paired with! They can tell you what works for them, and you can just adjust accordingly. For example, I'm paired with delta, and he mentioned Grooveshark or Youtube. I'm curating my playlist with that knowledge in the back of my head!
