Will be very useful make available a check button to restrict musictracker to send my "current listening" only to contacts who have the "now listening" protocol.

Why I think this is useful?

Today I have a lot of Google Talk contacts who use Gmail as IM client, and this contacts are spammed by my status changes.

Ex:

Me: Hello Mary, how are you?

Me - Track01 - Artist01 Me - Track02 - Artist01 Me - Track03 - Artist01 Me - Track04 - Artist01 Me - Track05 - Artist01

Mary: Hi! Are you showing your collection to me.. Cool, but stop!

Go to configuration on musictracker and put into status format %m in the begin and the end of them. Comment if that solves the problem

That's only a decent workaround if you don't use your status message for anything else.
