- Source
- Records catalogued in the Groovv app by its collectors, with release data from Discogs. Counts include private collections as anonymous aggregates; a collector is only ever named if they chose to be featured.
- Albums
- Different pressings of the same album count together: albums are grouped by Discogs master release, and a pressing without a master borrows the master of a same-title, same-artist pressing.
- Collectors and members
- Collectors are accounts with at least one record. Members are all accounts.
- Most collected
- Albums ranked by how many distinct collectors own at least one copy.
- New vinyl
- Albums first released in roughly the last 12 months, ranked by how many distinct collectors added them in the last 60 days.
- On the rise
- Only records added by collectors who have been on Groovv for 14 days or more, outside bulk imports (days with more than 50 additions), in the last 60 days. Ranked by how far those additions exceed the album's usual share, so long-standing classics do not win on size alone. New releases are left to New vinyl.
- Rarest pressings added
- Pressings added in the last 30 days with 200 or fewer copies registered on Discogs and at least 30 have-plus-want, so the count is trustworthy.
- Most wanted
- Albums ranked by how many distinct collectors have them on their wantlist.
- When the community listens
- Logged spins, at most three per record per day per collector, in the collector's local time (device time zone where known, otherwise estimated from their region), in 3-hour blocks. Each listener is weighted equally, so heavy loggers do not dominate.
- The long tail
- The share of albums owned by exactly one collector, and the share of collectors with 10 or more records who own at least one album nobody else on Groovv has.
- Originals or reissues
- An original is a copy pressed within one year of the album's first release. Covers albums first released before 2000 with 40 or more copies on Groovv.
- Coloured and heavyweight vinyl
- The share of copies by the year each pressing was made, in 5-year groups. Colour is read from the pressing's Discogs format notes, ignoring label colours, stamps and half-speed mastering notes. Heavyweight means 180g, 200g or 220g.
- Records people buy twice
- Albums owned by the same collector in two or more different pressings.
- Completist magnets
- The average number of an artist's albums owned by each collector who owns at least one, for artists with 40 or more collectors.
- Starter and deep crates
- Albums most over-represented in collections of 10 to 60 records compared with collections of 500 or more.
- Who cut your records
- Lacquer cutters come from each pressing's Discogs credits ("Lacquer Cut By"), ranked by how many collectors own a pressing they cut.
- Who pressed each decade
- Pressing plants come from each pressing's Discogs company credits ("Pressed By"). Shares are of the copies pressed in that decade whose plant is known, for decades with 500 or more such copies.
- Where it was recorded
- Recording studios come from Discogs company credits ("Recorded At"), ranked by how many collectors own a record made there.
- Privacy
- Every figure is an aggregate. No list is built from fewer than 5 collectors, and comparisons between collection sizes need 8.
- Updates
- Live figures refresh every 15 minutes; the collection, decoded refreshes daily; each month is frozen as an archive when it closes.
