Just wanted to mention that I spent my time creating a quick script earlier on so you can retrieve files from MP3Skull without having to tab out or anything. On /edit or /carradio, go to Radio Stations and then Custom and enter the following in the URL field:
[trackinfo] - replace this with the track you're searching for. If there's no results for a certain song then remove some key words due to artists placing copyright protection on their tracks.
trackNo - some songs on there have annoying ringtone versions and stuff so if that version isn't good enough then change this value to one higher up to go to a different version if it's available.
Example - searching for "r kelly fly" and choosing the first result:
I've made it so that if a search returns with 0 results, then you'll hear an actual message in a female voice. Hope it helps and if you experience any issues or find any bugs then drop a PM.
Just to let you know, I'm not responsible for what songs are retrieved so don't contact me asking to add more songs or anything.
