After my kids were toddlers (they're 9 and 6 now), we almost always queued up some Mozart for them at bedtime. No harm. Now that they are old enough to express a preference, of the things they get exposed to, they do exhibit peculiarly diverse inclinations.
They (predictably) seem to like pop music, including Barenaked Ladies and Jimmy Buffett. They have (much to my dismay) not yet embraced the Blues appropriately. My 6 year old son is a fiend for progressive rock (Yes, Genesis, Floyd, etc.). They both get subjected to jazz standards on a continuous basis.
Music is so cool.
