The standard 2009 CD is fine (16-bit). However, the Vinyl Master (12", 180-gram) is the holy grail. The dynamic range on the vinyl master is often less brick-walled than the CD. A needle-drop rip of that vinyl in 24-bit/192kHz WAV converted to FLAC is the definitive listening experience. Check specialized music forums for these rips (ensure they are user-created from personal collections).

Summary for collection identification: If you are verifying a download, ensure the 2006 Self-Titled and 2009 Love Drunk albums are present with and AccurateRip verification to confirm it is a "Proper" high-fidelity release.
