Music,you you never stop listening to...

I guess I don't understand the OP.
Is it actual recordings that are needed like mp3s?
Or was it for suggestions?
If it is the second thing I understand what happened in the case of Capricorn and Captain Beyond and the Allmans.
But a someone will have to explain to me how in the world Shake Some Action was not a mega hit.
Bet ya never heard it.
Getting the music isn't hard now a days.
