I have LPs that have locked grooves at the end of the songs where they keep playing the same loop until you manually stop them. At 33 1/3 RPM, they would hit 1000 plays after 30 minutes, they don't noticeably degrade in that period of time. A friend said he would leave records like that playing for weeks on the same locked groove and that they did eventually wear out. A week would be 7 * 24 * 60 * 33.33 so 336,000 plays.
