[Feature request] Notes for download availability

[Wilker-uwu]

i think that SoundCloud media should have in the Download button text, a note showing if the song is originally a free to download, a paid one, or if there was no link at all in the site. — e.g show as Download (No-link) if the upload did not mention any info about its availability nor gave a link, or show as Download (CC) if it is licensed under Creative Commons, or Download (Free, CC) if it is Creative Commons and it has a download link for the free download.

also the application should give the option to block or redirect (to the linked store or whatever) downloads of songs that are paid, with the text note shown in the same way as mentioned above.

I don't think this can be implemented without creating problems: looking for arbitrary links in descriptions is difficult and can lead to security problems if the parsed link leads to a malicious page.

i was thinking about just seeing the "free download"|"buy"|whatever buttons that usually appear in some uploads, not the ones in the description.

in any case, i think that the issue with security can be less of a problem if there could be a prompt like FairEmail does when opening any links, so the user can be alerted in case they might misclick or need to know where they're going with the link.

In fact it's really easy.
Look at this music, you can see a « Free Download » button.
Just add this method, if you want that feature, in SouncloudStreamExtractor.java

public isFree() throws ParsingException {
    try {
         return track.getString("purchase_title");
    } catch (Exception ignored) {
         return null;
}

It returns "Free download" for the track quoted above. If there is not that information, it returns null, such as with this music
