[Feature Request] Support gapless playback

[JuxGD]

Description

Some tracks, especially in LPs, end transitioning seamlessly into another track (segues). Symphony has a pretty short time between track but it's not instant, breaking the "seamlessness" of it. Spotify supports this for albums only. foobar200 also does this (don't know the details, @scytho mentioned this)

Solution

We could have a "gapless into next track" setting for individual tracks and playlists/albums, when it's enabled it loads the beginning of the next track ahead of time (some time before the current track ends) so it can start playing it the instant the current track ends.

Alternatives

Have it happen globally, without a setting for specific tracks and playlists/albums, this would be configured with a "time between tracks" setting

Additional Context

• Aetherborne LP from Chime is an album that uses segues for its tracks, you can notice it more starting from the 3rd track (Homeworld). This album is better experienced with gapless playback.

• This issue used to be called "Support seamless transitions (segues)"

Checklist

• I have read the [Contribution Guidelines]

I think, this is called gapless playback. foobar2000 does this. It is important for the listening experience, i.e. on Mike Oldfield’s albums or film music.

This is one of the few features I am really missing. Otherwise Symphony is the best and the most logically behaving player I have found so far.
