PLS,wats d difference btw EPs ,mixtapes and albums ? and what is a song recorded on another artiste's instrumentals called?

EPs - Short album, usually should be 3-5 songs. Max 30 mins. So basically a longer Single.

Mixtape - is basically a collection of songs with fresh material or other peoples' material which another person decides to remake. The big selling point is, whoever owns the mixtape cannot sell or make financial profits from it if it contains other people's material because it will require sample clearance and other business arrangements. Whereas if the mixtape contains hundred percent of the artiste's own work, the artiste can decide to sell it for example, Drake's "So far Gone" which came out as a free mixtape first and he later on decided to repack (mostly engineered properly) it and sell for $5. There were samples on the mixtape which Drake had to clear before he could sell it. That is why most artistes usually release most of their unreleased materials as mixtapes. The Weeknd did the same - repackaged his three mixtapes added three tracks and put it up for sale. Usually because they cannot get sample clearance for the song or is just a rubbish song.

Album - Lets just call an album your dissertation. Meaning, it is well referenced if you used sources, it is usually more than 5 songs and it should make for compelling reading. I hope that analogy explains what an album is. Lack of referencing is what causes artistes to be sued for making money of the album without paying royalties (sometimes, money isn't even exchanged but the original of the song must agree to your usage of their song in your own body of work).
