Some requests require authentification (as any user). According to [Discogs](https://www.discogs.com/developers/#page:authentication,header:authentication-discogs-auth-flow), to send requests with Discogs Auth, you have two options: sending your credentials in the query string with key and secret parameters or a [token parameter](https://www.discogs.com/settings/developers).
This is token way example:
```go
client := discogs.NewClient().UserAgent("TestDiscogsClient/0.0.1 +example.com").Token("Some Token")
```
Don't forget to set required currency ("USD", "GBP", "EUR", "CAD", "AUD", "JPY", "CHF", "MXN", "BRL", "NZD", "SEK", "ZAR" are allowed):
```go
err := client.Currency("EUR");
client, err := discogs.NewClient(&discogs.Options{
UserAgent: "Some Name",
Currency: "EUR", // optional, "USD" (default), "GBP", "EUR", "CAD", "AUD", "JPY", "CHF", "MXN", "BRL", "NZD", "SEK", "ZAR" are allowed
Token: "Some Token", // optional
URL: "https://api.discogs.com",
})
```
#### Releases
```go
release, err := client.Release(9893847)
release, err := client.Release.Release(9893847)
fmt.Println(release.Artists[0].Name, " - ", release.Title)
// St. Petersburg Ska-Jazz Review - Elephant Riddim
```
