As someone currently going through the process it ain't fun and, as was posted, 'amicable' is a misnomer.Currently listening to Dick Gaughan's SAIL ON '..only a fool breaks their heart for what has gone...' and The John Wright Band album 'Other Roads' which has half a dozen suitable songs.
For peace and quiet (even as a non-practicing Christian), Choral Evensong sung by a good church choir has much to recommend it.
All the best
