I either "grab" songs (not steal, I SWEAR I'M NOT STEALING) and change some instruments and things that make up the song (apologies to anyone who hates me for reasons I'm not aware of and for reasons I don't care for) or I take inspiration from songs I like and know of.
If I've made a mistake, or something like that, could you try to tell me through the comments of the sequences. The same goes for tips and advice regarding sequences and such.
note: I usually make songs in my free time.
(I can also make my sequences without taking much from the original song)
