Schubert lieder, Rachmaninov concerti, Liszt etudes, and the Beatles

It makes knitting a really inspiring, semi-self-indulegent time to appreciate the finer things in life.
If I'm charity knitting or knitting for friends, I usually have some style of worship music on, and I center my thoughts around spiritual relationships and prayer for the person I'm knitting for.
General knitting though, it's all about the best of classical music and my Beatles :D
