Albums that should never receive the 45RPM treatment!

[Johnny Vinyl]

Meddle, DSOTM and Abbey Road (side 2) come to mind right away.

And a question...what are the maximum number of minutes per side for a 45RPM pressing?

I see my 45RPM thread struck a chord. To my knowledge (though I am a bit of a novice), I think the maximum number of minutes per side really depends on how it is mastered. I purchased a Mondo Home Alone soundtrack which 45 RPM and has 6 songs on one side, so all I know is a lot more is possible than what current 45 RPM reissues are producing.

The running time of a LP side depends on the recording level of the mastering. If you want or need a longer running time, it needs to be recorded at a lower level.
