FAQ

Where are songs downloaded from? Despite what the title implies, songs are actually downloaded from youtube. The program retrieves the data of each song from spotify and uses a combination of the duration, title, artists, album, and views in special cases, to determine which songs on youtube correspond to those on spotify. You can find the algorithm behind this in Song.cpp under SearchForSong.
How accurate are the downloads? The downloads are almost always accurate and have only few times has downloaded the incorrect song being usually covers of a song. If the song is not on youtube at all, it will not download the song if there are no extremely similar songs in title, artists, duration, etc. After roughly 500 songs tested over many artists and genres I have only gotten around 5-10 incorrect which were all covers of songs that were not on youtube. You can find the algorithm behind this in Song.cpp under SearchForSong.
What can I download from spotify? You can download a playlist, album, or individual songs. Episodes are also unsupported if in a playlist/album (cannot be inputted manully), but there may also be other types of media that I have not found yet. You also cannot download all songs from a given artist but if you need to get around this the only suggestion I have is to compile all of their songs into a playlist and input that into the program but I may have a look into supporting this in the future. If you need any help finding the link for your music, there is a guide Here under Setup > How To Find Your URL.
What is the quality of the downloaded songs? The audio quality of each song can be configured in the settings ranging from 33-256kb/s in steps of 32 (excluding 33). The program downloads the highest quality stream from youtube usually being from 230-260kb/s and converts it to the desired quality.
Can I change the file extension of output files? No. Not yet at least. For now they will always be outputed as an mp3 file, but this is planned to change in the future and more file extensions will come in later updates. Currently there are some things in the code that are created specially regarding mp3 files and would not work with other file extensions (taglib with the metadata assigning as an example) and would need more work put into it to accommodate for more. For now I have other updates planned before regarding this, but it will definitely be a feature soon.
Why have there been months between updates? When I first created this project I has a lot of free time on my hands and was able to work on it for as long as I wanted, but now I have other responsibilities that are taking up a good chunk of my time and there are other projects that I work on outside of this one so I just do not have the time to work on this constantly. This project is being made out of passion and I do work on it often enough to now release updates hopefully monthly and if not bi-monthly, but do not let that put you off as I enjoy working on this project and no matter the breaks that I have taken, this will continue to be developed. If anything does happen where I am unable to work on the project anymore, I will update the readme to reflect that.
