Not to mention the AMOUNT of music on those albums, especially the doubles.
Islands, TFK's most recent album, a double album, fits on 2 CDs, and would fit on 2 LPs.
Unfold the Future, TFK's longest album, fits on 2 CDs, but needs 4, maybe 5 LPs, to fit it all.
An annoying trend over recent years is the tendency for bands and artists to put out a "double" album that is only mere minutes above the 80 minute threshold of CD capacity.
