It's hard to narrow it down to just 5. However, here are 5 that I love enough that I listen to them regularly.
5. Megalovania (Undertale)
4. Battle 2 (Final Fantasy 4)
3. Katamari on the Rocks (Katamari Damacy)
2. Metroid Opening Theme (Metroid)
There are many versions I like to listen to for this one, but here is one of them.
1. Aerith's Theme (Final Fantasy 7)
