Click here to show the 20 line(s) of Go which triggered the analyzer.
```go
for _, p := range ps {
for _, t := range ts {
playerLog, errs := p.Subscribe()
go func() {
for e := range errs {
// player errors are bound to fill up, should the connection be lost.
// TODO: find a better way to deal with player error logs
log.Println(e)
}
}()
for cur := range playerLog {
go func(cur playerStatus) {
fmt.Println("now playing:", cur.Track.Title, "by", cur.Track.Artist)
t.SubmitPlayingNow(cur.Track)
createTimer(p, t, cur)
}(cur)
}
