Ok so I release Spotify obviously wont want to give us a formal estimate of when the new app will be out. I understand that companies don't want to make promises they cannot keep, and saying they only want to release it when it is right is spot on.
On the other hand Spotify just doesn't work for ICS Android users. Previously Spotify have released a number of experimental and beta builds. So how about it Spotify? Get us an ICS compatible experimental beta and then all of us whingers on the Android forums can actually help by providing feedback.
And if it doesn't work well? Who cares as it doesn't work for us now anyway!
