Like you can read at minecraft wiki, the Record-Tag says which record is played, and the RecordItem-Tag which item the jukebox contains.

But if you use this command:

/setblock ~ ~ ~ jukebox 0 replace {RecordItem:{id:record_wait,Count:1b},Record:2267}

It wont play the record "wait"

Also when you break it, the record pops out, but when you put another record in it, the original record won't pop out

Actually it seems that the "Record" tag is really bugged, because when you do blockdata on a jukebox playing a record, it won't show the "Record" tag...
