Mixtape App?

[Noyu]

Hi. So I've been seeing this girl and I wanted to make her a "mixtape".

Something to remember me by while she goes on a trip with another guy (don't ask, very complicated situation).

 

I would've gone with a Spotify playlist but most songs on my list aren't even there (they're all on YT though)

What's the best way I could do this? Like maybe combine all the songs into one file and just send her the file to listen on her phone?

I have used http://123apps.com's audio joiner if you are just looking to combine audio files. If you can get the mp3s of the songs, if from YouTube perhaps a converter like http://en.savefrom.net, and then drop all of them in the joiner. Yes, it is oneline and not the best gui, but i have used it and it works just fine.
