But I figured it might be useful to someone out there if I compiled a list of music that was really good for revision, based on my efforts with Foobar and trying to cram all of Roman history into my head at once...
Ozric Tentacles - Erpland
Ozrics make excellent revision music! It's interesting enough to keep your brain ticking over, but doesn't get too distracting. Nicely relaxing too! I tend to prefer music without vocals (usually) for revision, but find a lot of music without vocals seems to be missing something - this isn't. This is just right!
