So far, the only way I can see to discover music is on the Featured list, which doesn't say what genre an album or song is in; though this is not a superb guide on other sites I've used, it's better than nothing. A list of genres and perhaps the ability to search within them would be great.

It would be better if you only paid if you listen to more than say 30 seconds of a track. That way you can try something, but if you don't like it and skip straight away, it hasn't cost you a precious penny

I can't see how to buy credits on the Psonar iPhone app.

I love the service but I've used up my free credits. I'd really like to buy some more so I can keep on listening!

When I have a track in my playlist and hover over it, I get a pointer suggesting I can click on it. When I click on it, nothing happens. When I click on it, I expect details of the track, album and artist to come up!

The system seems to work well, although there doesn't seem to be much of the music I listen to on here.

Create ‘music channels’ playing particular genres of music that you can subscribe to for music discovery.

It may just be me, but the website seems to be running really slow (talking 35 seconds to load the player)!

I mailed Martin on LinkedIn about this, although integration with Instinctiv (instinctiv.com) would be great. Their system tries to work out what music you are in the mood for listening to by analysing the tracks you skip.

Opened a link with a gifted song, but player had an error (screenshot sent via email). Still, the gifted credit to play this song seems to be gone, so I can't try again to play it.

My configuration: Chrome 15.0.874.120 m, Windows 7 32bit.

I just listened to a song on my iPhone after seeing Martin's tweet. I would have shared it, but I couldn't see any sharing buttons/links!

So the user can listen again if they want to

With the ability to listen / gift / share these playlists

Having received a gift, would be nice to be able to send a gift back.

Once in web app there could be a ‘My Gifts’ area where you can see music gifted to you and music you have gifted. You should be able to see the sender and recipient of gifts.

After sending a gift to a users, would be great to see when the user has listened to the gift

It's annoying to look up a track and get all the way to playing it before being told that I can't stream it in my country. It would be better if the tracks either didn't show up in search results, or showed up clearly greyed out or otherwise marked as unavailable.

Id like to know who king tubby is

Please
