Replace Tune doesn't check RID's, it just always replaces (I just realized I still need to check to see if this also updates the RID if it DID change -- it probably doesn't, so there may be a border case w/ duplicate checking when you're in the same session after a replace, but that's what 58 is for )

Replace Tune updates tags (but keeps FIDs the same)

On Jupiter, leading zeros are stripped from track numbers (I don't have my Jupiter hooked up to test this, but it SHOULD do this)
