If you absolutely need the track as number 11 in the metadata, use a tag editor (MP3tag, Kid3). After purchasing the correct FLAC file from a store (even if it's Track 1), manually edit the TRACKNUMBER field to 11 and the TRACKTOTAL field to 11 or 15 depending on your compilation. This allows the file to appear correctly on your DAP (Digital Audio Player) or car stereo.

Many audiophiles create compilation CDs for their car or high-end DAC. A user might have burned a custom FLAC disc titled "Imagine Dragons: Anthems." On that custom disc, "Warriors" is the 11th track. The search could be for that specific digital rip of their personal compilation.
