Breaks only work if you come back with a new look, sound and attitude and with quality, cohesive material.
janet., Ray of Light, Bangerz, The Rising (Bruce's 2002 comeback album which sold over 500k first week), BEYONCE to an extent (she took the standard 2.5 year gap between her releases, but she had been absent from radio since 2009), FutureSex/LoveSounds are proof of this.
If you take a long time and come back with, as we say, same chola but different skirt, you will flop
Everything we've heard is 7/10 or better.
