Some of the clean tracks like 2005-2007 and 2008 themes were originally available via 3 Mobile ($6/month for BB including live stream access, mp3 ringtone, and more). Then there was the 2003 Unseen, Uncut, Unreal DVD that had the 2003 bed.
There were probably lots of audio goodies that were missed on the old unencrypted satellite feeds on live show days as well - one 2007 eviction rehearsal was capped by someone from this and it had the walkdown bed mostly clean. I think it wasn't until 2008 that encryption was used (after the 2007 finale rehearsal was captured and leaked online). AI powered audio splitting tools can sometimes help remove unwanted noise but quality varies significantly. Nothing beats an original clean clip.
