Hi Team,

  Good day! Been wondring if you can find this song “FIRST LOVE” from PIRATE movie soundtrack. Sang by Christopher Atkins and Kristy McNichol. Would appreciate much if this will be granted. Cheers guys.

Hi @Ramon Menguito, unfortunately, the song "FIRST LOVE" from the PIRATE movie soundtrack, sung by Christopher Atkins and Kristy McNichol, isn't available on Deezer.

Our music acquisition is negotiated between artists and right-holders, and it's not something we have direct control over.

Remember, if you have an Deezer account, you can upload the song to your own MP3 section on Deezer, and then you can add it to playlists. The step-by-step guide is available here.

Feel free to reach out if you have any questions or need further help.

Hi Team,

There is no lana del rey’s version of song summer wine on deezer. Can you please add it? Would appreciate much if this will be granted.

Hi @emilija she did a cover of the song but it seems that she never released to major streaming services.
You can always add the song to your library as an MP3.
