Calling all Auditeers

A friend of mine has set me what on the face of it appears an impossible
task... 

>>I have had a bit of an idea. Let me know if you reckon it can be done. 

>>I have a very old tape with 'Get it On' by 
>>T-Rex followed immediately by 'All the Young Dudes'. 
>>Weirdly, the Hoople refer to the -Rex in their song.

>>Is it possible, do you reckon, to construct a tape
>>(or in these modern times a 'CD') with each concurrent 
>>song referring to the previous, as above, possibly 
>>either by band name or song title. 
>>I caught myself singing Blur's 'Country House' 
>>earlier, which contains the words 'Rat Trap', for instance

This sounds like exactly the sort of thing that has been discussed here, ad
nauseum I shouldn't wonder. 
Can it be done? What is the longest chain you could construct? 

Over to you,
