You are looking for a rip with these specifications:

Many fakes exist online (a 128kbps MP3 converted to FLAC is still a bad MP3). To verify:

Let’s be realistic: Mötley Crüe is now a legacy act. The band members (Sixx, Lee, Mars, Neil) have famously chaotic relationships with their back catalog. Universal Music Group, which controls the distribution, has shown little interest in releasing high-resolution versions of the 1998 Greatest Hits.

Consequently, the “exclusive FLAC” exists in a legal gray area.

If you love the band, buy a used copy of the 1998 CD on Discogs (median price: $8). Then, and only then, seek the digital rip for convenience.
