making a mix with only your best/favorite tracks ?
imo you're thinking too much in tracks then in the wholeness of a mix
i once had an opportunity to make a mixed-cd (not like GU fcourse, but a mix suitable for CD-R, with cover artwork)

but in my opinion, a blend of best tracks only is just that, it will prolly never be a best mix
