What do you want to do when you've finished? http://rulertube.fun/ rulertube.com This classical music series has the dubious distinction of containing by far the longest podcasts I’ve ever come upon, including one lasting a mind-bending 16 hours and 21 minutes. However, they’re made with love, and contain such musical gems – from a rather marvellous gothic symphony by a little-known British composer called Havergal Brian to dozens of pieces inspired by Shakespeare’s plays – that they’re worth recommending all the same. I tend to dip in and out at random; which is perhaps the only sensible approach unless you have several months to spare.
