I was really surprised that you showed three soundtracks for Champloo, since there are four in Japan (Departure, Impression, Masta, and Playlist - I actually bought these) and two in the US (Katana and Music Record 2). So I downloaded them all to see what was on them, and I just wanted to clear up any confusion.
The one you have labeled as the first OST, Katana, is actually Departure, OST 2/Music Record 2 is Impression, and OST 3 is Masta, though it's missing the last track, #19 - "You feat. Kazami" which is here:

The Playlist soundtrack, which you didn't have, is here:

And as a bonus, the last episode ending theme, "San Francisco" from Midicronica's album #501 is here:

and "Obokuri Eeumi" from Ikue Asazaki's album Utabautayun (from ep 14 when Mugen is drowning) is here:
