Honestly, when I started to learning guitar, I didn't know much about notes. It was something like a boring stuff for me. Actually, this is generally not boring. If you have the talence of sound, if you can understand the difference between the two same songs which sing by different people, you may have the "listening talent".
Notes make this difference and your ability better. When you see the note, you can play the same song faster then you imagine. But without the notes, everything would be hard.
Even though you don't need to learn the notes perfectly, you should learn them because they make playing easier 

I miss it hehe
