Wouldn't all random methods with some reasonable number of bits of randomness (eg 256) be unable to create all permutations of a sufficiently long playlist. The number of permutations of the playlist would be greater than the number possible random seeds. Eg a playlist with 60 songs has more than 2^270 permutations.
