So iMusic is new and created last. In subscribed list iMusic will come last. Anyway I have no idea what Airtel is doing with 2 offers this week. Let's wait and watch.
Maybe one offer for this week and 2nd offer for next week activated this week itself. Some weeks/months back Iam getting the feeling 2 offers were available in same week if am not wrong.
You could be right. imusic offer is now removed in app. It may be be launched on later date. Most likely English News offer this week. Also upcoming offer now also include LePlex, Recording, Combo Service (2 offers) and imusic.
